UEFI needs VFAT for the efi-partition.

Actually, you have an error or two below.

Probably better to wipe the file system. But you talk about moving away 
from EFI in another thread, so we'll just say that should this happen 
again, you should wipe with mkfs. instead of just rm -r.


Yes, this machine is new but I run it for a over 10-days, configured
most of the programs and it was running without much problems.
Yesterday, I decided to check some parameters in kernel .config so I run:
  genkernel --menuconfig all


Next time, just do this:

cd /usr/src/linux
make menconfig (or nconfig)


* Gentoo Linux Genkernel; Version 4.1.2
* Using genkernel configuration from '/etc/genkernel.conf' ...
* Running with options: --kernel-config=/proc/config.gz all

* Working with Linux kernel 5.4.72-gentoo-x86_64 for x86_64
* Using kernel config file '/proc/config.gz' ...

* Note: The version above is subject to change (depends on config and
status of kernel sources).

So you are wrong below. As you can see above, genkernel IS using 
/usr/src/linux/.config. I'm not 100% certain, but I THINK genkernel will 
compare the config files, and prefer the .config if it is present.

  >> Running 'make oldconfig' ...
* >> Compiling 5.4.72-gentoo-x86_64 bzImage ...


When I exit it it started to compile the kernel (it did not finish) I
pressed
"CTRL-C" (interrupted).
I didn't know then, but running genkernel --menuconfig all
takes configuration from:
/etc/kernels/kernel-config-5.4.72-gentoo-x86_64

not from: /usr/src/linux/.config
No, unless /etc/kernels/kernel-config- is NEWER than .config, 
and maybe not even then. See above.

However, NO FILE HAD CHANGED IN /boot
But this this is the moment, I couldn't boot correctly.

What was the boot error?

make && make modules_install
make install
genkernel --install --kernel-config=/usr/src/linux/.config initramfs
grub-install --target=x86_64-efi --efi-directory=/boot
grub-mkconfig -o /boot/grub/grub.cfg

But nothing had changed. So I tired newer kernel: 5.4.80-gentoo-r1-x86_64
But this time I run (without interruptions):
  genkernel --menuconfig all
grub-mkconfig -o /boot/grub/grub.cfg

And again nothing changed, root "/" still mounts "ro"

findmnt
TARGETSOURCE FSTYPE   OPTIONS
/ /dev/nvme0n1p4 ext4 ro,relatime

Normally it should be:
findmnt
TARGET   SOURCE  FSTYPE  OPTIONS
//dev/sda4   ext4rw,noatime,data=ordered
Looks like it's not getting to the root remount stage. The kernel will 
almost always boot in ro mode. So you're probably getting stuck in the 
emergency shell. Can you see your device in /dev?

Does dmesg show the drive being recognised, corresponding drivers being
loaded, partitions and filesystems recognised?

cat dmesg  |grep error
doesn't show any errors

What's the last 10 or so lines from dmesg when it fails to boot and goes 
to what I'm guessing is the emergency shell?

I'll try to boot GParted and see what comes up.



I don't think gparted is your answer. Sounds to me like something is 
causing it to fail in the changeover from your initrd to the actual 
drive. If that's the case I bet your partitions are fine. Can you show 
us the last 10-15 lines printed on the screen before you get stuck?

As long as your system is set to use legacy/bios mode instead of EFI 
then I don't see why not.

Re: [gentoo-user] switching from "refine" to "grub"

[Dan Egli]

I can not say for certain, but I imagine it would be something like this:

emerge -c refine
rm  -rf  
rm -rf /boot/refine
GRUB_TARGET="x86_64-efi" emerge grub
grub-install --efi-directory= --target=x86_64-efi
grub-mkconfig -o /boot/grub/grub.cfg


Of course you really should put the GRUB_TARGET in your make.conf, but 
in a pinch that will work. I'm assuming you are using a 64-bit EFI 
enabled computer. The grub steps I am sure of. I've never used refine 
before, so I don't know it.

[gentoo-user] UEFI system - installing Grub without EFI

I was trying to check VFAT boot partition on my disk with Gparted but it

Can I format the VFAT to EXT2 and install grub on it without EFI?

When you "wiped /boot" did you reformat the partition?  If yes, did you 
recreate a filesystem label with the same name as used in your /etc/fstab?

Is this a brand new kernel image + initramfs, or a kernel image which you have 
used at least once before to boot this machine successfully?

Does dmesg show the drive being recognised, corresponding drivers being 
loaded, partitions and filesystems recognised?

Does syslog show any relevant errors?

Does 'mount' or 'findmnt' show all your partitions?

Are they mounted as rw?

These are just some steps you could follow to find out at what stage a problem 
may have occurred and what to check/fix to get it booting successfully.

PS.  These days there are precompiled kernels + initramfs available to get a 
system booting quickly, like sys-kernel/gentoo-kernel-bin, before you finesse 
a slimmer kernel manually later on - should you ever wish to roll your own by 
hand.

I'm using now linux-5.4.72-gentoo, grub only. Install boot loader from

I only use genkernel to install initframes:

No, errors during startup in dmesg.  So I have very little to go by.

This is part of the python cleanup/upgrade already discussed at length on
this list over the past week, so the answers are already available. You
have had some useful replies already but one thing I noticed it that this
is brought about by bzr, which is no longer in portage. Unless you have
it installed from an overlay for a particular need of yours, you should
let it be depcleaned.

I would have thought all modern boot loaders can read ext* filesystems, 
without needing to specify the filesystem type by passing the kernel 
parameters yourself to the boot loader.  However, I don't use genkernel to 
know how to configure/modify it so it boots with different boot managers.  If 
the details are not explained in the links I provided above, someone 
experienced in using genkernel should give some pointers.

I feel your pain, as I have often sweated over messages emerge spews out at 
me, which tends to happen mostly when I do not have the time to delve into 
fixing it!  I sometimes also find these messages to be unintuitive (for me) as 
I struggle to decipher 'portaguese'.  :-)

There was a recent python upgrade, which caused a lot of packages with python 
as a dependency requiring an update or to be rebuilt.  Other users were also 
caught up in this.  A recommendation was to run emerge with '-U', rather than 
'-N', which may produce a smaller list of packages to update.

Have a quick look at:

and in particular the section "Necessary USE flag changes", but also look at 
the output of the package which complains about change of USE, with eix, e.g.:

The output explains what USE flags the package was installed with and what 
other flags are available.  Other tools also show USE flags, e.g. 

$ equery u dev-python/pycparser

Also, taking a look at the ebuild file could reveal similarly useful info:

PYTHON_COMPAT=( python3_{6,7,8,9} pypy3 )

It means the particular package was installed with some USE flag, which is now 
incompatible with the current version of the package or one of its 
dependencies.  You'll need USE="+python_targets_python3_7" to be able to build 
it.  Therefore you may need to intervene to change a previous USE flag setting 
to allow that package to rebuild/update.

In cases like this I tend to grep quickly my /etc/portage settings to see if I 
have configured manually a USE flag, which is no longer needed;  e.g. 
python3_5 - then unset it, unless you have a particular reason to force this 
USE flag for some package which you need on your system.

grep python*_ -r /etc/portage

I understand "dependency required by" to refer to package B, which is a build 
time dependency of package A.  Package B also requires a change of USE flag, 
besides package A.

(If I got this wrong someone will chime in to correct me).

I would interpret the message you got to mean:

Well, what portage is trying to tell you is that you need to change or
add a file  in your /etc/portage/package.use directory to specify
dev-python/pycparser python_targets_python3_7
and that should fix it  -- and if you have --autounmask-use =y (which
is the default) it should write the changes for you and after fixing
up your package.use file or directlry if necessary, you can proceed.

I hope that helps.

So I'm totally guessing here but as you have no other responses yet:

I'd start near the 'top', which of course is near the bottom.

What is 'bzr'?

https://packages.gentoo.org/categories/dev-vcs

I do not see 'bzr' on this page. Is it something left over in your world
file, or just installed by some other app and no longer used, or moved to
some other package category?

If you don't know what it is and think you don't need it then if it were me
I'd consider just removing it and letting emerge @world figure out how to
proceed.

And all of that is just a guess. No Gentoo available right now to delve
further.

Best of luck,

[gentoo-user] Gobbledegook error message from emerge.

[Alan Mackenzie]

Hello, Gentoo.

I'm angry, because I've wasted several hours trying to decypher a wholly
unintuitive error "message" from emerge.  Because of this, it's been too
long since I've been able to update.  Help, please!

The command I typed in was

# time emerge -auND @world.

I got back a horrendously long list of packages to merge (most of them
re-merges), followed by:

emerge: there are no ebuilds built with USE flags to satisfy 
"dev-python/pycparser[python_targets_python3_6(-)?,python_targets_python3_7(-)?,python_targets_python3_8(-)?,python_targets_python3_9(-)?,-python_single_target_python3_6(-),-python_single_target_python3_7(-),-python_single_target_python3_8(-),-python_single_target_python3_9(-)]".
!!! One of the following packages is required to complete your request:
- dev-python/pycparser-2.20-r1::gentoo (Change USE: +python_targets_python3_7)
- dev-python/cffi-1.14.0-r3::gentoo (Change USE: -python_targets_python3_7)
(dependency required by "dev-python/cffi-1.14.0-r3::gentoo" [ebuild])
(dependency required by "dev-python/bcrypt-3.2.0::gentoo" [installed])
(dependency required by "dev-python/paramiko-2.7.1::gentoo" [installed])
(dependency required by "dev-vcs/bzr-2.7.0::gentoo" [installed])
(dependency required by "@selected" [set])
(dependency required by "@world" [argument])

.  What is the syntax and semantics of that first line?  Is it explained
somewhere in the emerge manual?  What do the square brackets mean?  What
do the commas within these square brackes mean?  AND?  OR?  What about
the question marks following minus signs inside parentheses?

What does "(Change USE: +python_targets_python3_7)" mean?  Is it a
suggestion to me that I should change some USE flag somewhere?  Or is it
telling me that a changed USE flag is the reason for all the trouble?  Or
does it mean something else?

What is "dependency required by" supposed to mean?  I can understand a
dependency of A on B.  I can understand A being required by B.  But a
dependency being required?  what does this mean?

Presumably to get out of the mess I've got to do something with one of
the packages which "is required to complete your request".

Surely somebody in the Gentoo portage team must see that printing human
readable error messages is a worthwhile thing to do.  Surely?

The error is indicative of the kernel driver for the / block device missing.  
If it is not built in-the-kernel, but as a module, then it should be in 
initramfs.

Copy the kernel image, System.map, .config and corresponding initramfs to the 
/boot partition, then point your boot manager to the kernel to boot it.

Of course it makes it a bit difficult to turn the PC _on_ after it's
been powered down unless you change the BIOS to "always on after power
interruption", then you can turn it on by toggling the AC power.

Is the CPU going to be the same?  The responses already cover the
mainboard itself well.  If the CPU could change then you need to check
your -march in CFLAGS for compatibility (if you set it) and
potentially rebuild anything you don't want to break.



How would I do that?  Would I have to set up a cross-compiler toolchain?


I don't remember the details, but what I'd do is set the CPU to 
something basic like x86_64. Then do an "emerge -e system", so at least 
enough is there to guarantee your system will boot.


Then, if the new system does fail to get beyond the basic command line, 
you can change the CPU back to native, do an "emerge -e world", and you 
should have your system back.


Bit of a long-winded hassle, but it should work ...

I've also seen where people had two or more switches in series and they
all had to be pressed at the same time to power off.  I've seen people
do that with reset buttons too.  It's just a momentary switch and ebay
has them by the dozen pretty cheap.  It's effective.

But, if one wants to really disable it, your way is easiest.  It just
depends on how far a person wants to go with this.

Now, when I boot I get a message:

Block device UUID=d32946b3-2236-4998-80dd-68b7d78e0c7b is not a valid
root device.

I did not change anything in /etc/fstab

Thank, will definitely try it and let you folks know.
But right now, I've managed to break the boot-loader, so this is the
priority.

Nowadays (e)logind handles that. Setting 
  HandlePowerKey=ignore
in /etc/elogind/logind.conf should disable that (haven't tested).

I am using "refind" (not grub)
With refind, do I need to run any special command to set-up correct kernel.
Here is my tree:  (grub is there, but I'm not using it)

Re: [gentoo-user] system won't boot - --no-bootloader set; Skipping bootloader update ...

[Dan Egli]

you didn't specify grub2 on the command line or (my preference) in 
/etc/genkernel.conf. So genkernel assumes you don't want it to fix your 
boot loader. If the kernel and ramdisk are all built, you can fix grub's 
config with grub-mkconfig -o /boot/grub/grub.cfg. For future kernel 
builds, read the paramaters in man genkernel so you know how to specify 
the boot loader, or just edit /etc/genkernel.conf and set the bootloader 
from none to grub2.

I installed sys-power/acpid  and wanted to double check the kernel

The ACPI option was enabled so I exit the menu but it started to compile the

Upon rebooting the X will not start no root login, just a screen with login:
"joseph (none)"

I bootstrap the PC and run:  genkernel --menuconfig all

What went wrong?
