Hi,

if you have Gentoo already installed on the box, make sure that you
configured the same compiler version as on the build host (gcc-config)
and then run:
gcc -### -march=native -E /usr/include/stdlib.h 2>&1 | grep
"/usr/libexec/gcc/.*cc1"

Everything after "-march=..." should be what your gcc version would use
when using march=native on the laptop.

Re: [gentoo-user] Anyone running a hardened profile?

[Hinnerk van Bruinehsen]

Hello walt,

I've running hardened (hardened profile + kernel (including pax and grsec)) for
at least 5 years on all my boxes except one (my gaming only box).
It's been quite a while that I had an issue caused by the hardened profile that
wasn't due to my fiddeling around with stuff like SELinux and the like. Even
these problems were all relatively easy to solve.
Truth be told: I guess that you won't even notice the hardened profile unless
you also run a hardened kernel (while still having increased security).

Hello,

you can try lsmod to see which modules actually get loaded (possibly even
before and after successful suspend - just in case there is a difference).

On the other hand you could check the kernel versions of the working kernel and
the new one and try to downgrade your kernel if necessary: my t510 doesn't wake
up from suspend to ram (I never tried hiberation) since at least 4.1.3

I had to time to bisect/investigate, but it worked fine with 4.0.y.

 should be able to install chromium. Apparently icu is pretty annoying.
 
 Alternatively, you could just uninstall qtwebkit if you're not using it

Re: [gentoo-user] Clashing dependencies in KDE

 Hello list,
 
 Today when I ran my usual upgrade I ran into a problem. Portage told me it 
 had skipped net-libs/libkgapi:4 because of unsatisfied dependencies. All it 
 could tell me was that =kde-base/kdepimlibs-4.14:4 required it.
 
 So I embarked on one of those fruitless cycles of adding packages to 
 package.keywords, one at a time as they caused portage to stop, until after 
 about 8 additions I hit the inevitable show-stopper. The mixing of versions 
 of parts of KDE resulted in both 4.14.3 and 4.12.5 of kdelibs being required

 It looks as though someone has allowed something from ~amd64 out of the wild

 thought it might be chromium, since libkgapi is for handling Google

 version.
 

Hello Peter,

if I'd be in your place I'd try to run emerge @world -uvDNta (the most
important one here is the -t for showing the dependency tree, you could also
play with --backtrack=30 to resolve possible issues with the dependency
calculation), after you removed the keyword stuff you just added.
From your fist statement (required by =kde-base/kdepimlibs-4.14:4) I guess
that you keyworded something that depends on kdepimlibs or kdepimlibs itself in
the past.
Another option would be to try equery d kdepimlibs : it should show everything
that depends on it (and you can crosscheck that with your keywords).
As a final straw (or first option - depending on you preferences) you could
resync the tree: maybe you've gotten an incomplete version/revbump that already
is resolved in later versions of the tree.

 Moin Hinnerk, 
 (hopefully have guessed this greet correctly...I am from that

 I have the source of the driver exclusivly compiled for 3.8.13
 as for 3.14.something (cant remember). 
 3.14.x has some other problems (on that embedded platform) like
 not powering off when shutdown, random reboots and such.
 So decided to go back to 3.8.13.
 Yesterday I started updateing (eix-sync and emerge) that Gentoo
 and it ends up in an endless loop (bash update) of configureing
 (damn slow on that mini iron) and compiling - as it looks -
 of a single file.
 After more than 10 hours I CTRL-C that, reupated and now I am
 ...updateing the bash again.
 Sigh.
 Currently fun is something else...
 
 Is the 3.15.10++ branch free of things like random reboot and
 not powering off?

Moin Meino,

(you've hit dead on spot: is there another valid greeting except that one?
;-) )

Right now I don't have a beaglebone black so sadly I can't provide any first
hand experience.
A 10 hour configure loop definitely sounds fishy to me. I'm running
a (hardened) Gentoo on a Raspberry Pi right now and I do compiling natively
most of the time (as it's not a that critical machine). As it's an even more
mini iron I know that it can be time consuming (maybe interesting: bash: 25
minutes, 57 seconds for 29 merges).
My rpi runs on a 3.16.3 kernel and my experience is that newer kernels help
immensely if available (that is if the hardware is either supported upstream or
there is a vendor branch testing new kernels). Especially for arm there is much
better support lately.
I find for less used platforms (read: not-x86/amd64) the newer kernels are
often more stable than stable ones because the latter often doesn't
experience much testing.

So in the end there aren't many more options than just try it out (kernel
builds are quick luckily because - as you stated in your other reply - kernel
builds are very easily cross-compilable).

Good luck/Viel Erfolg,

 Now the first one is image-copied to the second one with dd,

 Then the first one is put into my embedded system, boots up and
 the normal eix-syn/emerge/compiel is done to update the system (whch
 takes a longer time becaus this is an embedded system).
 
 Will I get a technical identical working and valid copy of the first sdcard

 the second sdcard if I rsync the relevant partition of the first onto
 the second sdcard.
 
 Or will I produce crap this way? Is this valid Gentoo-wise?
 

Moin (again),

this will work quite well, at least if you take care (I used this way for
moving my systems to new drives or even via network to different boxes (in the
latter case CFLAGS and kernel config will become important again, as you can
imagine)).
Ideally you should run rsync with the option to remove files not found on the
source drive (otherwise you'll likely clutter the target with stale files
(especially documentation  but also older library versions).
You will also need to change the configs (at least static network  hostname,
possibly more) so that both systems don't clash, at least if you plan to run
both on the same network.
The rm option of rsync is potentially dangerous (e.g. you can delete files
from home).
If you are careful this is a valid way of doing that. Another option that would
move quite a bit work from one machine to the other is just building binpkgs on
one host and use the other one as binhost. That way (if you use identical
/etc/portage dirs) you can quite savely use portage and nonetheless negate the
use of compiling (there will still be the load of dependency resplution,
extracting etc).

 One of the main maintainer for the Beaglebone black kernel sources

 I am now back to kernel 3.8.13, where this stuff runs...
 (The kernel I tried it before was 3.14.19)
 But this kernel version get no much updates thess days and is 
 somehow old...
 
So you tried to run a driver for 3.8.x on a 3.14.x kernel?
Such things often result in breakage as, while the kernels interface to
userspace is very stable, the internal interfaces aren't stable at all. Likely
there would be some other stuff necessary to get the driver to work properly.
Some googling around led me to [1] though, which seems to imply that there is
support on newer kernels (3.15.10 and newer), if you use the right patch...

So maybe you are sucessful with that...

 Stabilization of GCC is especially careful because if your GCC winds up
 broken, you might not be able to fix it (emerge won't work).
 
 And since GCC is used to build everything else on your system, it can't
 go stable until all upstream packages are fixed or patched to work with
 the new GCC.
 
 There's usually a tracker for those packages. For gcc-4.9 it's at,
 
   https://bugs.gentoo.org/show_bug.cgi?id=gcc-4.9


Since gcc is slotted (I actually have 4.7, 4.8 and 4.9 on my systems). That
argument doesn't count much, imho.
I personally didn't encounter a single breakage after updating from 4.8 to 4.9
(this was different from 4.7 to 4.8).
IIRC 4.7 isn't supported by upstream anymore and there are known (security)
bugs. I don't really know why not at least 4.8 is stable.

I've taken a look at the bug that is mentioned in the error and there were
several things mentioned that are supposed to fix this:

1. disable auditd (if you have it running) - this was the newest (from 
'14)
   So if you have it installed run /etc/init.d/auditd stop
2. reemerge several packages because python may have issues:
   - sync your tree
   - emerge portage (which will likely pull in some python stuff if the 
box
 wasn't updated for some time)
  (- optional: run eselect python and select a sane version and run 
python
  updater - this wasn't mentioned but may make sense nonetheless)
   - emerge linux-headers
   - emerge glibc (hopefully with success this time)

 I didn't have the audit stuff installed BUT it was turned on in the
 kernel.  I kicked that out and also got rid of all that cgroup stuff I
 don't have any need for.  Rebooted then tried your list.  Audit stuff,
 gone. Sync is maybe a couple days old so should be OK.  Portage is up to
 date.  Python as follows:
 
 dev-lang/python-2.7.6
 dev-lang/python-3.3.3
 
 localhost ~ # eselect python list
 Available Python interpreters:
   [1]   python2.7 *
   [2]   python3.3
 localhost ~ #
 
 Updated linux-headers.  It was a little out of sync with kernel
 version.  After all that, I get this:
 
SNIP
 
 So, the locale junk is gone but glibc is still not liking something. 
 Where did I put that hammer the last time I used it??  ;-) 
 
 Ideas?  I'm pretty much out of them right now.  My idea is the hammer. 
 lol 

Generally hammers tend to make things worse... ;-)

Can you run;

 printf #include unistd.h\n#include sys/syscall.h\nint main(){return \
 syscall(1000)!=-1;}\n  syscall.c  make syscall  ./syscall  echo $?

(It should be all one line).
It will compile the test that seems to fail on your system and runs it,
expected output would be:

cc syscall.c   -o syscall
0

The 0 says that all went well, if it reports something else then it's not
just the buildsystem...

If it's the system you'll have to reinstall glibc (no kidding, as it provides
the used headers (though they should be somewhat dependent on linux-headers)).

You could do the following to break out of this chicken-and-egg-problem:
you can download an appropriate stage3-tarball (x86 or amd64) and extract it to
some arbitrary location. Then you essentially do the same as if you would
install gentoo from scratch (bind mount dev and sys and mount proc) and chroot
into it.
Inside the chroot you sync your tree (you could also bind-mount it from the
default location) and emerge glibc again but this time with the --build-pkg
flag set (emerge --buildpkg glibc). As long as you kernel is new enough (which
3.15.5 definitely is) the build should succeed and leave you with a nice binpkg
of glibc sitting in path-to-chroot/usr/portage/packages (in case of the
bind mount it should also be there inside your real system). If needed copy
it to /usr/portage/packages and run emerge -K glibc (this will force portage
to use the binpkg).

I hope that this es enough to circumvent the check (if not you could also try
to boot your rig from usb and copy the contents of the binpkg manually).

If the build breaks even inside the chroot run uname -a and take a look if the
kernel you're running acutally reports to be a 3.15.5 one.

Good luck,
Hinnerk

Re: [gentoo-user] glibc-2.17 fails and warning: setlocale: LC_ALL error

[Hinnerk van Bruinehsen]

On a side note:

You can also boot into a chroot, move your /etc and /var directories elsewhere
(e.g. etc_old and var_old) (do the same for other directories where you
yourself made changes), extract a stage 3 tarball on top of your normal
/ directory (overwriting potentially broken stuff), move etc_old and var_old
back to their old locations/names, chroot into it (like during install) and
emerge @system @world -evDNa (to rebuild everything from the known-good start
that the stage3 provides).

Hi Dale,

first you should check if you have this line in your /etc/locale.gen: 
en_US.UTF-8 UTF-8

If you do, run locale-gen to create the locale. This should in theory fix the
LC_foo errors (Note: there are some LC_ settings best left undisturbed,
especially setting LC_ALL to something other than C tends  to break stuff).

The other error you get (glibc failing to install) seem to be caused by an old
kernel version that wouldn't be compatible with the newer glibc. So I'd
recommend that you try to update your kernel first.

I looked at that file.  On both my systems, it is not a text file.  When I

This is interesting.  I'm using this version:  3.15.5-gentoo According to
equery, that's as new as it gets.  I thought about going back to a older
version but that seemed odd given the error.  I been dealing with this for
about two days now.  My 3 lb mini sledge is starting to look interesting. 
@_@
 
Thoughts?

That's interesting: maybe that kernel is too new. Which version of glibc is
installed right now (It may be helpful to make a guess which kernel version
should work). Otherwise according to the Changelogs of gentoo-sources and glic
the kernel version was something around 3.6.x when glibc-2.17 was added to the
tree.

Hi,

try updating system and world at the same time. You have packages in system on
which other packages in world depend. Try emerge -uvDNa @system @world
If that doesn't help add backtrack as stated in the error: emerge -uvDNa
@system @world --backtrack=30

Most likely this will solve your issues. If not you could unmerge blocking
packages but imho that's not a neat way. I'd rather emerge some selected
packages manually (gobject-introspection and vala would be good candidates in
your case) [use -v1 or you'll end up with a horribly cluttered world file].
If that doesn't work either it may be possible that there is no working upgrade
path due to a too large version difference. In that case you could try to
emerge intermediate versions manually (emerge -v1 =atom-version)...

iotop shows io ( AS in reads and writes to disk). The only memory related info

There are some other options of nesting as well. You can use backticks ` or
$(...) to run a command inside another. An example would be emerge `qlist -CI
x11-drivers`  (or the equivalent emerge $(qlist -CI x11-drivers) ) . This would
run qlist -CI x11-drivers (lists installed packages of the category
x11-drivers) and use this output for emerge (which will effectively result in
reinstalling every package from the x11-drivers category).

 For /usr you don't need a live CD, because the contents of /usr shouldn't
 change unless you instal/remove something. You can make sure they don't
 change during the merge by remounting read-only

 mount /usr -o remount,ro
 mkdir /newusr
 rsync -a /usr/ /new/usr/
 Comment out /usr line in /etc/fstab
 mv /usr /oldusr
 mv /newusr /usr
 reboot
 rmdir /oldusr

 What you do with the old partition is up to you. In this case the
 discussion was about /usr on LVM, so you just delete it and allocate the
 space elsewhere when needed.



You can even leave out the step of creating a new directory and moving it later
if you bind-mount you rootfs somewhere, e.g. /mnt/gentoo.
You may want to add some parameters to the call to rsync, though (e.g. those
that preserve permissions, xattrs (especially for SELinux or XT-PaX) and
owner/group (should be -pogX), possibly -x aswell (if you have other
filesystems under /usr (e.g. a discrete FS for the portage tree).

This would boil down to:

mount /usr -o remout,ro # just to make sure there are no changes
mount -o bind / /mnt/gentoo
rsync -apogXx /usr/ /mnt/usr/ # possibly fiddle around with the flags
comment out the /usr line in fstab

if everything's working: delete the old usr-partition (or do with it whatever

 Does portage keep a todo list anywhere?


Hello Helmut,

you are encountering a relatively new feature of portage that is supposed to
make revdep-rebuild and emerge @preserve-rebuild obsolete.
The logic is, that if you update a package, other packages depending on this
package will automatically rebuild to prevent breakage.
It seems that in your case portage thinks that one of that packages depends
on zsh-completion and pulls that in for rebuild which in turn, most likely via
setuptools or PyQt4  pulls libreoffice to rebuild.

Because python is interpreted my guess is, that this rebuild would be
unnecessary. You can try to figure out the package via equery d atom,
starting with zsh-completion itself.

It may be possible that you can dodge the rebuild by emergeing zsh-completion
with the --nodeps option.

Hi,

I did - I had some problems, but I'm not sure if they were caused by the
combination of ZFS and hardened. There were some issues updating kernel and ZFS
(most likely due to ZFS on root and me using ~arch hardened-sources and the
live ebuild for zfs).
There are some hardened options that are known to be not working (constify was
one of them but that should be patched now). I think another one was HIDESYM.

There is a (more or less regularly updated blogpost by prometheanfire

So you could ask him or ryao (he seems to support hardened+zfs at least to

You should definitely determine the right value for ashift on pool creation
(it controls the alignment on the medium). It's an option that you afaik can 
only set
on filesystem creation and therefore needs a restart from scratch if you get it
wrong.
According to the illumos wiki it's possible to run a mixed pool (if you have
drives requiring different alignments[1])
If in doubt: ask ryao (iirc given the right information he can tell you which
are the right options for you if you can't deduce it yourself).
Choosing the wrong alignment can cause severe performance loss (that's not
a ZFS issue but happened when 4k sector drives appeared and tools like fdisk
weren't aware of this).

 How did the system boot then?

Most likely your /boot partition is not ext2 as stated in fstab and it
therefore fails to mount (the unsupported optional features hint in that
direction).
Simply try to mount it by hand (mount /boot). If that fails try to mount it
with option -t filesystem (for filesystem try ext3 or ext4).

Your system still boots because grub is able to read the filesystem (which
makes corruption unlikely). grub doesn't use fstab or the drivers in the
kernelimage (which isn't even loaded at that point of time).

 Is anyone able to elaborate on this, please?
 
 I think I've had a eureka! moment of understanding whilst preparing to 
 compose this reply, but I've always been sceptical of these kinds of 
 statements in the past.
 
 Surely flash memory devices must present themselves to the o/s as block 
 devices, because that's how all storage devices work, right?
 
 If I'm now understanding correctly, SSDs present themselves to the o/s as 
 block devices more or less as convenient or necessary. They can be treated as 
 such as long as all the data required is listed in the file allocation table. 
 I'm left wondering how the SSD knows that a file has been deleted, and 
 whether this works for all conceivable file-systems.

The problem is that you can't delete on a flash cell. The process is
simplified: read cell - delete to be deleted stuff in memory - write
memory contents back.

Since flash cells can only be written to a fixed amount of times
(afterwards they become unreliable) there is a concept called wear
leveling. This means essentially that your 128 GB flash drive in reality
hasn't just 128 GB of storage but e.g. 256GB. To spread out the writes
it reads one cell, does the memory operation and write the contents back
to another cell while marking the old cell as unused.
This means two things: you can't really delete something securely
(noteven with tools like shred) and you can't access overwritten data
(because it's now inside the unused-marked area).

There is a special command (TRIM [1]) that does the marking after
something was deleted to counter perfomance degradation.

Fun fact: most SSDs that offer a secure delete feature (whole disk)
don't really delete anything but are internally encrypted and throw away
the encryption key and generate a new one on receiving the secure delete
command which leads to unreadable data and therefore is a kind of secure
deletion (unless the underlying crypto is broken).

The actual numbers were made up to make the point (maybe I should have
stated that in my OP). According to [1] they are normally between 7% -
37%.
Linux supports TRIM since Kernel 2.6.28. It's supported for several
filesystems (Ext4, Btrfs, FAT, GFS2 and XFS) but must be enabled via the
discard mount option. I don't have definitive information for Windows
but it seems to be supported by at least Windows 7 (as far as I can tell
without any user interaction).
Since the deletion happened under Windows I made a guess that it is
not totally unreasonable that dd may not work (if the deleted data would
have been TRIMed).

necessarily stored linar so it's not said that a new partition is using
the same memory cells as the old one. Even if it is, you'd lose any
information about directories or files (names, dates, accessrights and
so on).
You should definitly try to minimize writes (ideally there would be
none) since they can corrupt data. For a HDD I'd advise to create a copy
using dd but from my understanding of SSD technology it's not
guaranteed to copy the right (now unused marked) blocks.
If you can't recover the old partition information I'd say you lost your
data unless you are willing (and there's no guarantees either) to pay
substantial amounts of money to specialised services (substantial as in
most likely  1000 EUR).

Re: [gentoo-user] About to embark on x32

 So I'm about to try setting up the x32 arch in a VM. I notice there's no

 Does anyone know of any notable differences between the setup process
 for amd64 and x32, or should I expect things to be relatively smooth?
 

I think that there are some problems with packages that rely on assembly
code (as there would have x32 specific assembly) so you get either
unoptimised binarys (if assembly is just for performance reasons) or
compilation will fail at all.
That was the reasoning why it's ten years too late (back then the same
problem existed with x86_64 - the asm needed to be ported).

Since there is no error it's hard to debug anything. You could try to

Inside there is the complete build output and therefore the error

If you cannot isolate the error yourself you could send the entire build

Sounds fine up to here. Make sure you have a line source

Step 2:

layman -a printer-drivers

Now the printer-drivers-overlay should be installed correctly.
Check if /var/lib/layman/make.conf contains:

PORTDIR_OVERLAY=
/var/lib/layman/printer-drivers
$PORTDIR_OVERLAY


maybe it has got other newlines or indentation, but the contents

Try:
emerge ebuild-name

 OK, so I get a new Brother MFC-6710DW printer, which includes

 Amazingly, I found an overlay that looks to be for a brother 
 printer that is identical to mine, except it down not have the

 Here it is on zugaina (Successfully synchronized overlay

 http://gpo.zugaina.org/Overlays/printer-drivers/

 I thought once that layman is setup you could just update the
 tree_list of packages (which I did) and then just use emerge to
 install from a give Overlay repository? (Yes, I modifies the
 /etc/make.conf
 
 #LAYMAN PORTDIR_OVERLAY=/usr/local/portage source
 /var/lib/layman/make.conf (but this layman make.conf file is still
 empty)
 
 So, I get this error: # layman -f -a

 Overlay net-print/brother-mfc6490cw-cups-1.1.2_p2 does not
 exist. (I also tried the name net-print/brother-mfc6490cw-cups to
 no avail)
 
 Next, I've manually downloaded the ebuild to: 
 /usr/local/portage/net-print/brother-mfc6490cw-cups/
 
 
 
 PROBLEM --- But I cannot use emerge to install it. # emerge

 So now I need to hack the manifest and other files into this dir? 
 Any discussion, ideas, syntax or ebuild support files (manifest et.

 Note: it's been a while since I've used the laymen scripts et. al. 
 so it's entirely possible I missed (fudged_up) the steps I gleaned 
 from the myriad of wikis  to do this install.
 
 rusty on Overlays, James
 

Hi James,

you'll have to add the complete overlay, e.g.:


layman -a printer-drivers

Afterwards you should be able to install the driver. The alternative
route would be to set up your own overlay. If you put a file inside
the normal portage tree, it will be removed after the next sync.
To create a Manifest you could issue ebuild path/to/foobar.ebuild
manifest but as stated above it would be removed on the next sync, if
you don't setup your own overlay. The easiest way would be to simply
add the overlay with layman -a overlayname. If I recall correctly
you'll have to update the list of available overlays before doing so
via layman -L

Ok - you're trying two different approaches at the same time. I'd
recommend you to just use the printer-drivers overlay.

Normally layman should take care of the contents of
/var/lib/layman/make.conf. Maybe it doesn#t work because you created
an empty one. You could try to simply delete it and afterwards rerun
layman -a printer-drivers. If that doesn't solve your problem,
recreate the  file with the following content:

PORTDIR_OVERLAY=
$PORTDIR_OVERLAY


Afterwards try layman -a printer-drivers again.

I can remember that I had to reactivate mine a while ago (maybe two
weeks).
Afterwards it worked again as expected. You should check afterwards,
if your system-compiler is still the right one (and maybe reactivate
it, too - I just did it without checking first). Now I have two
asterisks marking gcc-versions (in different colors, if I recall
correctly).

 So the page at [1] is a little wrong because it misses the boot

In theory grub2 is able to open a luks-encrypted volume though it
seems to have some disadvantages: you'll need to enter the passphrase
(or pass the keyfile) two times, because grub itself needs to decrypt
the volume to get the later stages from the encrypted volume and
afterwards the decryption in the bootprocess itself takes place.

I can't give any real advice about it though, because I use an
unencrypted boot partition. Depending on your needs it could be an
increase of security, because you can stop an attacker from injecting
malicious code into your kernel (or replace it completely).

 I don't think so, I still can replace your bootloader and grab
 your password. If you really think you might need something like
 this, I suggest you put your kernel and bootloader on a USB stick
 and boot your machine from that. When not in use keep the stick on
 your person.
 
 That still does not protect you from physically tempering with your
 device.
 
 Anyway, what about one those fancy tin foil hats to protect
 oneself against the governments mind control rays :)
 

Ah yes - the aluminium foil deflector beanie
(http://zapatopi.net/afdb/)...

I just use it, when going out of my house or when updating my
MindGuard (http://zapatopi.net/mindguard/)


Enough fun - I just wanted to name the possibility because it's there
and it would't require you to repartition your drive.
I think it would be an increase in security nonetheless, though you're
correct: there are a lot more possible attack vectors with side
channel stuff getting very freaky indeed (i.e.: there is an
interesting paper about using the gyroscopes of a mobile telephone to
make a (80%) correct guess about the pressed key)

 Okay, I have setup so far this:
 
 /dev/sda1 - /boot (unencrypted) /dev/sda2 - swap (not yet setup,

 /dev/sda3 is the underlaying drive, where I used gpg:
 
 # gpg --decrypt key.gpg | cryptsetup --verbose luksFormat
 /dev/sda3 # gpg --decrypt key.gpg | cryptsetup --verbose luksOpen
 /dev/sda3 encVol # dd if=/dev/zero of=/dev/mapper/encVol bs=100M
 (to avoid filesystem corruption) # mkfs.ext4 -L root
 /dev/mapper/encVol
 
 Now I continued as usual with the Gentoo handbook (mount all, copy
 things on it, etc.)
 
 After I compiled the kernel, emerged cryptsetup on the new system,
 I editied /boot/grub/grub.conf: 
 --- default 0 timeout
 30 splashimage=(hd0,0)/boot/grub/splash.xpm.gz
 
 title Gentoo Linux root (hd0,0) kernel
 /boot/kernel-genkernel-x86-3.3.8-gentoo root=/dev/ram0
 crypt_root=/dev/sda3 initrd
 /boot/initramfs-genkernel-x86-3.3.8-gentoo 
 --- (I read not to use
 real_root, but crypt_root instead?)
 
 Then I emerged grub as usual (also: # cat /proc/mounts  etc/mtab )
 and did: # grub-install --no-floppy /dev/sda
 
 Still as usual. Now it is downloading plymouth (to have some cool
 things) + dracut (easiest way as I read in wiki).
 
 I also had to expand /etc/make.conf (not /etc/portage/make.conf ???
 Is this a mistake in handbook?):
 
 --- 
 DRACUT_MODULES=crypt_gpg plymouth 
 ---
 
 Now I really hope, that after I installed dracut on it, that I can
 boot it and the initrd will be updated. It needs at least some
 kernel modules (e.g. dm_crypt, ext4, sha512_generic, aes_generic)
 plus gpg and cryptsetup tools to actually decrypt the hard drive.
 
 Regards, Roland
 

I thin you need to add crypt as a dracut module since crypt_gpg is
afaik just an extension to crypt.

The output from equery seems to support my assumption:

...
dracut_modules_crypt : Decrypt devices encrypted with
cryptsetup/LUKS
dracut_modules_crypt-gpg : Support for GPG-encrypted keys for
crypt module
...

 Turns out, I was wrong in thinking the immediate problem was
 solved. In fact, the system just booted of the memory stick without
 me noticing. I've now finally solved by re-creating the boot
 partition without MiB-alignment, just good old cfdisk. So, the
 working partition scheme looks like this:

 Is there an explanation for this?
 

Hi there,

if my eye-integrated diff doesn't deceive me the problem was, that
your old bootpartition was ntfs. Since grub doesn't support ntfs
that's an easy explanation.
Your boot partition is the first one on the drive, isn't it?

I would try to recompile the kernel. You should also set the
/usr/src/linux symlink accordingly (to your actual kernel sources).
Reboot to machine after rebuilding the kernel and then rebuild the
module itself.
Maybe try - as Wonko stated in another mail - module versioning support.

For the whole process make sure that you use a consistent toolchain
(gcc, linux-headers, kernel-sources, glibc, binutils come to mind)

 What does it have to mean? I am not getting smart.
 
 Usually, it means you have compiled a module which is not the same 
 version as your running kernel -- make sure your /usr/src/linux is
 set correctly.
 
 Hope this helps.
 

You could also check for which kernel the module is compiled by
issuing modinfo path-to-module

since the error is ImportError: No module named setuptools you
should make sure, that dev-python/setuptools is installed (for the

If it's installed you could try to run python-updater.

Why not simply get you data on it and use it for about 2 weeks? Maybe
you should mirror important stuff to the old drive for that time.

After about 2 weeks of normal usage you should be well out of the
beginnig of that bathtub curve (I always had problems when copying
data to the new drive when I had a bad one, except DOA of course).

 Does it not display any errors?
 
 No - no errors, straight to the grub2 command line.
 
 This menu entry looks good to me (only difference here is kernel
 version, UUIDs and root partition). Sounds like it may not be
 installed correctly... just to confirm here are the few things
 you should have to do:
 
 1. Edit /etc/default/grub Perhaps disable quiet stuff and any 
 graphical settings just for now. 2. Run grub2-mkconfig -o
 /boot/grub2/grub.cfg 3. Run grub2-install --no-floppy
 /dev/sda
 
 Yes that's what i did. No changes to default/grub though.
 
 If you have another hard drive it's possible the order is
 different from when you installed grub, but this would give an
 error
 
 Its a single disk system, and grub1 was fine before i installed
 grub2.
 
 I am assuming that if i don't need an initrd in grub1 i likewise
 don't need one in grub2.
 

It hasn't got anything to do with initrd or stuff like that. The grub
menu comes way before that.

To show the menu there are 2 things that really matter:

- - there must exist a file /boot/grub2/grub.cfg . The important thing
here is the 2: Since Gentoo supports slotted installs of both grub2
and grub legacy it has a different path for grub2. Afaik that's a
fairly uncommon way of doing it (ubuntu and the like use
/boot/grub/grub.cfg).
If you installed grub 2 via portage you should make sure that the path
contains the 2 - if not you could try ist without it.

- - the file has to be sane - the one you posted earlier looks fine,
though. You could try to generate a new one via grub2-mkconfig -o
/boot/grub2/grub.cfg nonetheless.

 What component could it be? Or is there some way to dig in?
 
 Could be anything, actually. Perhaps the Southbridge (or whatever
 its nom de jour is) which IIRC handles the sound system. (Because
 Pulseaudio is also having trouble).
 
 Rgds,
 

I have similar problems with pulseaudio (seemingly random crashes

 Many thanks for sharing your experience, Helmut.
 

Do you want to resize the partition or do you want to delete and
recreate it?

The second option is no problem, the first could lead to some data
loss (if you are unlucky).

 I'd like to delete and recreate ONLY the first partition (which is
 small). The question is, can I keep the other partitions.
 
 As far as I remember, I once deleted the extended partition and
 tried to recreate logical partitions at the same place. But that
 didn't work.
 
 Helmut.
 
 

If the first partition is a primary partition it's no issue. If it is
inside a extended partion it gets tricky, because the extended
partition acts like a kind of container.

- From your description I guess it's a boot partition, which normally is
a primary one. In that case just delete it and recreate it afterwards.

Note: you may need to reinstall you bootloader afterwards (due to the
changed partition data) and don't forget to toggle the bootable flag
for that partition.

If it's an extended partition I fear that my experience doesn't
suffice to give you qualifield hints as I try to avoid them.

You could also change the bash script:

it resides in /etc/grub.d/10_linux

the relevant part is:

case x$machine in
xi?86 | xx86_64)
list=`for i in /boot/vmlinuz-* /vmlinuz-* /boot/kernel-* ; do
  if grub_file_is_not_garbage $i ; then echo -n $i
 ; fi
  done` ;;
*)
list=`for i in /boot/vmlinuz-* /boot/vmlinux-* /vmlinuz-*
/vmlinux-* /boot/kernel-* ; do
  if grub_file_is_not_garbage $i ; then echo -n $i
 ; fi
 done` ;;
esac


as you can see there are 2 parts: one für x86 and x86_64 and one for
the rest.
If you add it to the list it will find everything, you could even call
it my-personal-kernel.

You only should add the path as well (/ or /boot/).

I've doing so for the initramfs for a while (I  have one static
initramfs which don't need to be updated for every kernel since my
config disables kernel modules).

Works fine. - You should only remember to look at it after a grub
update (though normally etc-update and co take care of that)

Yes - to both

- - you can mask the slot for grub2
- - you can install grub2 (that is the binaries) and continue to use
grub legacy (until you issue grub2-install device).

Personally I use grub2 for at least 2 years (1.97 or something like
that) and encountered few to none problems.
I find it even more comfortable (due to automatic config generation).

Alternatives? Hardly, I think. There are some lightweight variants:

- - sys-libs/uclibc
http://www.uclibc.org/

- - dev-libs/dietlibc
http://www.fefe.de/dietlibc/

comes to mind, but afaik they don't have the full functionality of

you should be able to use:

ebuild path-to-ebuild/glibc-2.14.1-r3.ebuild package

Quoting the manpage:

package
  This command is a lot like the merge command, except that
after fetching, unpacking,  com‐

created and stored in PKGDIR (see
  make.conf(5)).

You may need to set PKGDIR.

To put it simple: if you want to use one of cgi,cvs or subversion,

Ok, I'll try t explain it:

 The following REQUIRED_USE flag constraints are unsatisfied: cgi? (
 perl )

First: it states that a REQUIRED_USE flag is not set. That means that
some functionality depends on a special useflag.
The next line states, which useflag is the one in question and which
useflag it needs:
You could interprete cgi? as If cgi is set, then test for the
following and ( perl ) is the flag which is tested.


The rest is simply for more information:

  The above constraints are a subset of the following complete expression:
cgi? ( perl ) cvs? ( perl ) subversion? ( perl ) webdav? ( curl )

It follows the same syntax, though.

I hope this si helping...

If you google you'll find some other patches (even one on

I normally issue something like

cat /var/log/emerge.log | grep -i compiling | tail -n 1

from another terminal. It shows the last package for which compiling
started. if you change the -n 1 to -n 2 it'll show the last 2 packages
(if you leave it out, you'll get the last 10).
You could also replace compiling with i.e. merge (then it'll look for
another part of the build process.

Otherwise (like Walter stated) most terminals within X (that I've
tried) add this info to the titlebar.

Hi,

as far as I can tell it works mostly. There are some packages which
seem to break:

- - firefox and thunderbird, if I remember correctly
- - chromium (theres an open bug on bgo)
- - hardened-sources: the neccessary gcc-plugins don't work because they
can't find the right symbols because gcc-4.7 is normally compiled with
g++ which mangles the symbols. Don't know how to work around that,
though it seems to be possible to compile gcc-4.7 with gcc - I just
don't know how

For all packages which break it's possible to switch to your old
gcc-version (unless you uninstall it).

Have you tried a make clean on your sourcetree?

CHK include/linux/version.h

IS for me one of the first lines I get at all. It seems strange to me
that you get a call to the linker (LD) before even a call to the
compiler (CC).

I'd suggest you try a make clean first and try to build again
afterwards (with -j1 or without a statement for jobs) to rule out race
conditions.

If that doesn't help, move your kernel sources to another directory
and reemerge the sources. Copy your .config (ideally one of a working
tree) and try again. If that doesn't help, try to get a working
default config (like from /proc/config.gz from a live distro).

 Hi,
 
 I'm trying out grub2 for the first time on my old laptop. I'm 
 following the guide at:
 https://wiki.gentoo.org/wiki/GRUB2_Quick_Start which seems easy
 enough. Basically just emerge it, install and go.
 
 However... two different questions:
 
 When I did this from a chroot, I just got the GRUB prompt upon 
 rebooting... no menu or anything. I can manually type linux 
 /boot/vmlinuz root=/dev/sda3 and then boot into my system. When I
 run grub2-mkconfig from within the chroot, I don't get any Found
 linux image lines. It does not create /boot/grub2/grub.cfg but
 rather grub.cfg.new. So I don't know if it's confused about where
 /boot is or what. Is there a trick to installing/updating grub2
 config from within a chroot?
 
 Second, when running grub2-mkconfig from within my working gentoo 
 system, it fails with error: failed to get canonical path of 
 /dev/root. which is apparently because I don't use an initramfs.
 I must manually run ln -s /dev/sda3 /dev/boot before it will
 work. Is there any trick to avoid having to do that every time? For
 now I have simply added that to my after-kernel-update script but
 I'm curious to know if grub2 knows how to handle this on its own
 somehow.
 
 Thanks, Paul
 

If I recall correctly you need to mount /sys for grub2 to sucessfully
detect devices.
mount -o bind /sys path-to-gentoo/sys should suffice.
proc and dev should be mounted according to the manual.

If you use a /boot- partition mount it, when you are inside the chroot.
Doing so it worked like a charm for all devices I installed that way
(3 in the last 3 months, if I recall correctly).

With kind regards,

 For me it did, half a year ago, several packages failed to build due to

 Libtool uses this variable without unsetting it before, and SystemRescueCD

 Apart from that, I really like SystemRescueCD.

Did you do env-update  . /etc/profile after entering chroot?
I always thought that setting the right environment variables was the
purpose of that.

I personally an Ubuntu-Live-Thumbdrive, because some time ago (2 years
or so) it wasn't possible to install gentoo with LUKS on a btrfs volume
from the gentoo minimal cd.

The advantage of a live cd (especially for a beginner) is the
possibility to read the manual and google problems while installing.
Another possibility to do that would be an installation via ssh (works
nice too).

You should be able to install an old version via a custom overlay. The

I would warn you to use it with caution since flash has a long history
of vulnerabilities and normally it should be one of the last packages
to keep a version from the stoneage (for flash it translates to older
that 2-26 weeks, normally).

 OK, How to find out which controller I am using at the moment
 whilst using a live CD? I have successfully chrooted into my system
 from a Mint Live CD, so I should be able to inspect my system
 either using Mint utilities or the Gentoo ones.
 
 Thanks, Ignas
 

You could try lspci

I would recommend to try it from the live cd (because under gentoo you
may need to emerge it first - otherwise it doesn't matter).

Within the output search for something like SATA Controller or PATA
Controller. If you can't find a matching driver google for the output
of lspce and kernel module.
If it's a SATA device in most cases the generic AHCI
(CONFIG_SATA_AHCI) seems to work.

You could also try lsmod though the problem is, that you would need to
know the names of possible modules.

 So, my habit is to have /usr sit on top of LVM on top of mdraid. I

 my systems ready before that.
 
 Now, having looked at the pertinent documentation, it looks like
 the command I need to run is:
 
 genkernel --lvm --mdadm --disklabel initramfs
 
 and then add the initramfs to my grub setup.
 
 The trouble is, genkernel dies on me. I tried for some feedback in 
 #gentoo-chat, and DrEeevil gave me two clues:
 
 13:34 +DrEeevil that shouldn't even be possible 13:36 +DrEeevil

 I don't know where to take things from here. I'm hesitant to file
 a bug on b.g.o, because the tail end of genkernel.log specifically
 says not to file build errors as bug reports.
 
 So...any ideas? This is an amd64 mostly-stable system, and dracut
 is still masked on amd64, which is why I'm trying to get genkernel 
 working.
 
 I've attached genkernel.log
 

You could try to add:

sys-apps/busybox static
sys-fs/mdadm static
sys-fs/lvm2 static

to your package.use and re-emerge the three packages. Afterwards try
it again and see what happens...

 What happened is it broke again, with no obvious signs of the
 cause. conf-update reported only trivial changes to three
 files.
 
 I've just tried it on my netbook and the same happened, but I
 think I'm closer to the cause. The three files in /etc/pam.d are
 login, passwd and su. After updating, there were ._cfg* versions
 of these files, but no originals, so conf-update just deleted
 them. It turns out these were owned by shadow but now belong to
 pambase. I suspect that pambase installed them as ._cfg versions,
 because the others already existed, then shadow removed the
 originals as they were no longer part of the package.
 
 Whether this is a bug in portage, the ebuilds or conf-update is
 open to debate, but conf-update ought to handle the situation
 better. I'll file a bug later if no one beats me to it.
 
 First, thanks for the warning.
 
 There is a bug filed
 https://bugs.gentoo.org/show_bug.cgi?id=412721
 
 The comments there say that if you run etc-update right after the 
 emerge all is well (but this isn't sufficient for people who use 
 screen, detatch, and log out).  Someone also mentioned
 dispatch-conf working.  No one mentioned cfg-update, which I use
 (and I believe neil does as well).  Could the problem be dependent
 on which configuration file updater one uses?
 
 I have not updated my primary machine.  I did update another one
 (both machines are ~amd64) including a cfg-update -q, but have not
 rebooted it.  The secondary can su.  This seems to suggest that
 cfg-update is sufficient in some cases.
 
 Am I correct in believing the safe procedure is to add
 
 =sys-auth/pambase-20101024-r2 =sys-apps/shadow-4.1.5.
 
 to /etc/portage/package.mask (or a file in that directory)?
 
 thanks, allan
 

Hi,

I actually used cfg-update -u on 3 different machines up to now.
So cfg-update can't be at the core of that problem.
Maybe it's some kind of race-condition or the bug depends on other
things too (e.g.: I'm using gnome and gdm also puts some files to
/etc/pam.d which maybe mitigate the issue somehow) - pure speculation,
though.

The syntax for the masking seems to be correct (since shadow-4.1.5-r2
already has hit the tree maybe the problem is solved. Otherwise you
would most likely like to mask -r1 and -r2 also).

Before etc-update severaly login-related things didn't work for me (su
not possible for example). After running etc-update everything seems
to work fine for me (e.g. selinux and gnome3).
I must confess that I didn't use sshd on my laptop so I can't say
anything about that.

With kind regards,

 That seems like a (possibly) helpful clue.  When you
 downgraded, did you do etc-update again, or were you asked to?
 Did you run it after the original upgrade?
 
 No, no and no.
 
 Just to confirm, are you saying that you did *not* run etc-update 
 after the original upgrade?  I remember clearly from this morning 
 that etc-update asked me to replace some files in /etc/pam.d, and I
 said yes to all. (I don't understand pam well enough to disobey 
 orders ;)

 Hi,
 
 is there a command which shows all dependencies of a package?
 
 Unfortunately, qdepends doesn't do the job, e.g.
 
 qdepends kde-base/kde-meta shows no dependencies at all while there
 are more than 200 of them.
 
 Many thanks for a hint, Helmut.
 

Hi,

equery can do it for you:

equery depgraph package

short is:

equery g package

The default settings are a depth of 1, showing only direct
dependencies. You can customise it by using --depth, e.g.:

equery g --depth=4 kde-meta

equery is part of gentoolkit
