As long as /boot is not on RAID, or is on RAID1, you don't need an
initrd. I've been booting this system for years with / on RAID1 and
everything else on RAID5.
From my research on the topic (I also wanted to have both /boot
and / on RAID1) there are the following traps:
* there is an option for the kernel that must be enabled at
compile time that enables automatic RAID detection and assembly by the
kernel before mounting /, but it works only for MD metadata 0.96 (see
[1]);
* the default metadata for `mdadm` is 1.2 (see `man mdadm`, and
search for `--metadata`), so when creating the RAID you must
explicitly select the metadata you want;
* indeed the preferred may to do it is using an initramfs; (I've
posted below some shell snippets that create do exactly this: assemble
my RAID); (the code snippets are between {{{...}}}, it's from a

Also a question for about /boot on RAID1... I didn't manage to
make it work... Could you Neil please tell me exactly how you did
this? I'm most interested in how you've convinced Grub to work...

Re: [gentoo-user] Questions for my first ebuild
Walter Dnes wrote:
I intend to get the Silicon Dust HDHomerun dual tuner box. It has a
linux library and CLI plus a separate gtk+ GUI. The linux source comes
with a makefile that puts stuff in /usr/local. But I want at least a
wrapper ebuild so that Portage knows about the files, and can manage
them. I'd prefer to write my own ebuild rather than depend on somebody
else to always have the most recent version supported somwehere in
layman. I've RTFM'd a lot, including
http://devmanual.gentoo.org/ebuild-writing/index.html but am still
unsure about a few things. Here's my setup so far...
* The latest file is
http://download.silicondust.com/hdhomerun/libhdhomerun_20100213.tgz
(underscore instead of hyphen, bleagh).
* I've set PORTDIR_OVERLAY=/usr/local/portage in /etc/make.conf
* I've actually created /usr/local/portage/media-tv

Now for the questions...
1) do I need to create /usr/local/portage/distfiles?
Nope. DISTDIR is /usr/portage/distfiles, even for overlay ebuilds.
2) the provided Makefile is supposed to put everything into the
/usr/local hierarchy. Does portage/emerge over-ride that, and if so,
what do I have to do to get send all files to the /usr/local hierarchy?
Don't know.
But... AFAIK, '/usr/local' is not a location favored by ebuilds. On my
server it's virtually empty:
~ # find /usr/local/ -type f -exec qfile '{}' \;
app-portage/layman (/usr/local/portage/layman/.keep_app-portage_layman-0)
I'd attempt to have my ebuild install to /usr. Most probably that's a
very common procedure when moving from barebones makefile to portage. If
make can't help you w/that (e.g. --prefix /usr or something like that),
try browsing other ebuilds. qgrep is a handy tool for that.
3) any glaring errors ?
I intend to pick it up next week, so I won't be able to test it
immediately. I do want my laptop to be ready to go when I bring the
tuner box home.

Everything above (su,sudo,policykit,polkit) are just sugar for permission bits (owner,group,others+SUID,GUID); attempting to give finer control over the permissions or provide convenience services. Mess up the configuration and you may as well hand out the root password. They're much better than manual management though, which is unless you're forty-two security wizard in one body you will get it wrong. Most security holes in Linux comes from a SUID program that lets untrusted programs into the trusted-space. 53 SUID or GUID programs on my system! Why does cdrecord have SUID set? No idea. I found sudo, although very handy for desktop, is a huge security hole. And is inadequate for any secure system. This is simply because if you run a program as sudo, then in the next five minute you start a malicious program *without* sudo; the malicious program can gain root access by stealing your previous sudo's timestamp (yes, it can steal the timestamp without being explicitly invoked with sudo[1]). Before running a potentially untrusted program, you must explicitly kill your sudo timestamp with `sudo -k` or set sudo to not use timestamp. Better yet, don't use sudo on secure systems. Wow... I never thought about that. I run sudo on my system 4 to 6 times a day if not more. Can tell me the setting please. Setting for the timeout? See `man sudoers` and look at timestamp_timeout. Setting for allowing program to steal timestamp? Don't worry, it's already default. I had a quick look at man pages and Gentoo docs but I did not see it. Gentoo sudo guide [1] could use a update about this. it was right under my nose but I missed it... If some leaves they PC for 5 mins you could run nano ~/.bashrc and add export PATH=/home/user/.bin:$PATH then make a file called sudo write something to nick the password and by it on to sudo and then clean up after it self. I believe the developers of `sudo` considered security against malicious people with physical access to the computer is out of their scope. Problem is, that means malicious people only need to trick a sudoers into running a piece of complex code and say you're not running my script with sudo, so the script can't do no harm to system. When I first used sudo, I thought by invoking sudo for trusted program only and omitting sudo for everything else and thought the system would be secure. That's a false sense of security. As long as you're a root-sudoers, all program you run can gain root access any time they need to. They just need to daemonize and poll every few minutes for an updated timestamp. Just for fun I did that to one of my terminal tabs, with the script running echo HAHA!. I once written a script that have this in the first line: if [ $UID != 0 ]; then sudo $0 quit fi # do business that requires root the script runs without asking password if I still have active timestamp from running another program. How convenient! (and makes me shivers)

[gentoo-user] Random failures: lvremove
Hi, I'm using LVM, having / and /home as logical volumes and a backup script creating a logical snapshot volume of each in the process. Since I use gentoo (comming from arch), my backup script fails rather often with the error message 'Can't remove open logical volume volume'. The script worked fine on arch before. The partition setup did not change. Sometimes it works fine, sometimes it just fails. As a workaround, I let the script just lvremove the snapshot three times with 5 seconds sleeping between the tries and the overall success rate for the script improved... The chance is about 40% lvremove succeeds at a given time and doesn't seem to in- or decrease when calling lvremove successively with a five second delay, though if it fails once, it tends to fail again more often if called within the next two or three seconds. Here is an example of the command failing once more after the backup script aborted. The second time it works. I did NOTHING but the commands listed below in these 30 seconds or so: (note: dmsetup says open: 0 in the first place!) kira namor # dmsetup info -c vg-snap_root Name Maj Min Stat Open Targ Event UUID vg-snap_root 253 5 L--w01 0 LVM- ayg5GD1dYyrkkan1pLa8WszI7UrQpy9YE2ynOTtHoSNckKdehm3XMIgkw7p8z69X kira namor # lvremove /dev/vg/snap_root Can't remove open logical volume snap_root kira namor # lsof /dev/vg/snap_root kira namor # fuser -a /dev/vg/snap_root /dev/vg/snap_root: kira namor # lvremove /dev/vg/snap_root Do you really want to remove active logical volume snap_root?

Yes, you should be able to, installing Gentoo is basically just copying a bunch of files to a partition in a harddisk, nothing magical.

We're on the cable giant Comcast's network and they are quickly moving toward removing nearly all Clear QAM from their transmissions meaning we will be left with very little that the HDHR can tune. Some people report on the Myth lists that they are down to little more than OTA and cable access channels. It hasn't happened to me yet, but I think the writing is on the wall. More Comcast people are moving toward the cheap DTAs and controlling them to change channels, but that's SDA only. HD requires a STB. What a mess!

It isn't something you activate. It's the way the drive is made. However the drive responds to 512 byte sector addresses. You can use it as you would any other drive, however... 1) If you put your partitions on 4K boundaries the drive will be fast 2) If you put your sectors on 512 byte boundaries the drive will work but be very slow Either way it will work. I think #1 is better, but that's up to you. Simple answer about what to do? Make sure the starting address of all partitions is divisible by 8, or for simplicity have every partition starting address end with 3 zeros which is what some of the newer Windows setup tools are doing. I know the 3 zero thing sounds like you're wasting space, and you would be, but it's very small compared to the size of the drive so it's what I did. Now, if you have NOT already purchased the drive, my suggestion is that you do not, or if you insist on buying some get in touch with me. I have 6 sitting right here at home that I'll happily sell to you at reduced prices. ;-) These drives are saving power by parking the heads very quickly and my experience over the last few months is that they are likely going to wear out in about 18 months according to WD's spec of 300K park cycles. (Check SMART data yourself) Additionally they are completely unusable for any sort of RAID environment as WD removed all the TLER functions from the firmware.

To use it, one needs a tool made by WD which only runs under windows. Or? Is this new sector size is something, which I can activate be using fdisk/mkfs or something included in the linux kernel since stone age and is only new to the guys at Microsoft/Winchester Digital? Can I take any advantage of that? Thank you very much for any help and advice in advance! Have a nice sunday! mcc Sort of none of the above. 4K sectors are 4K sectors. It isn't something you activate. It's the way the drive is made. However the drive responds to 512 byte sector addresses. You can use it as you would any other drive, however... 1) If you put your partitions on 4K boundaries the drive will be fast 2) If you put your sectors on 512 byte boundaries the drive will work but be very slow Either way it will work. I think #1 is better, but that's up to you. Simple answer about what to do? Make sure the starting address of all partitions is divisible by 8, or for simplicity have every partition starting address end with 3 zeros which is what some of the newer Windows setup tools are doing. I know the 3 zero thing sounds like you're wasting space, and you would be, but it's very small compared to the size of the drive so it's what I did. Now, if you have NOT already purchased the drive, my suggestion is that you do not, or if you insist on buying some get in touch with me. I have 6 sitting right here at home that I'll happily sell to you at reduced prices. ;-) These drives are saving power by parking the heads very quickly and my experience over the last few months is that they are likely going to wear out in about 18 months according to WD's spec of 300K park cycles. (Check SMART data yourself) Additionally they are completely unusable for any sort of RAID environment as WD removed all the TLER functions from the firmware. Linux is racking up 1 cycles every 2 minutes.

Do the following in a terminal window from your working system. 1) Plug in the new drive. 2) Boot your machine as usual to the old Gentoo. 3) Run fdisk on the new drive to make partitions you want on your new system (fdisk /dev/sdb). 4) Make your file systems with mke2fs and mkswap, then run swapon /dev/sdb?. 5) Make all the mount points for all your partitions, but instead of doing it on your new drive do it on your old drive in the /mnt directory (mkdir -p /mnt/sdb/boot /mnt/sdb/tmp /mnt/sdb/usr /mnt/sdb/var . . .) and make one extra mount point for your old system bin (mkdir -p /mnt/sdb/oldsysbin). 6) Mount the directories on /dev/sdb from /dev/sda (mount -t ext3 /dev/sdb7 /mnt/sdb/usr). 7) Mount your old system bin for the tar command. My tar is in /bin and /bin is on (df -k /bin) /dev/sda3. Run mount -t ext3 /dev/sda3 /mnt/oldsys/ to mount the bin directory. 8) Make the stage4.

If all went well you should now be able to unplug either drive and boot to the other. I would boot to the old drive first to make sure that still works as if nothing happened. Then shutdown, unplug the old drive and plug in the new drive. See if you can boot to the new drive. This should be a mirror image of the old drive with the new partition sizes.

I don't think it will affect the original system and it should allow you to work in another terminal while your building the new drive. Does this make sense. Let me know if it works. Good luck, dhk

Only root can run the setcap program to add capabilities to a program, at least on a normal, UNIX-style security system. On a role-based security system, even root might not be permitted to do this. If I had the root password to own system(which I do...) and I wanted Wine to uses IPX without running as root. I would set setcap cap_net_raw=ep /usr/bin/wine as root. Then I could run Wine as my normal user. No one in there right mind would run Wine as root. If you did you may as well use Windows. You say no one in their right mind would run Wine as root. But if you did not have capabilities support available, and wanted Wine to use IPX, then you wouldn't have any other choice but to run Wine as root. By using capabilities, you aren't increasing Wines permissions, you are decreasing the permissions needed to support IPX. Trying to compare Wine without IPX to Wine with CAP_NET_RAW isn't a fair comparison, as the two don't have the same feature set and thus clearly don't have the same security needs. Or explain it like this: The kernel can do anything the software and hardware supports. Normally, the Unix kernel gives those same rights to any app running with UID 0 (NOT the same thing as the root account - that's just a label. To prove it, create a new account toor with UID 0 and log in as it). Unix permissions are traditionally an all or nothing approach. You can do what root can do, or you can do what users can do. This got modified with the introduction of groups and group owners a long time ago, where a user could get the rights of the group owner of an app/file is they were members of the group. Please note that it's the kernel doing this, not the root account. The kernel trusts the root account and does what it says. But traditional Unix permissions have the problem of not being fine-grained enough. For the most part this works fine, but in the odd case where you need more, you are up a creek without a paddle and have to give everything to get a little. That's why we have SUID and it's bastard progeny GUID. A more ridiculous solution is very hard to find. So this whole argument about do caps raise or lower permissions? is utterly pointless and leads nowhere. It's not even the point, as there are two viewpoints and one seems to go up and one seems to go down. caps do this: Allow fine-grained access control to resources, without having to give everything to get something. -- alan dot mckinnon at gmail dot com

Why are you doing that?
Because it wasn't a minor bugfix update? I'm going from 4.1.2 to 4.3.4.
So what?
Is there an ABI change between 4.1.2 to 4.3.4 that causes apps built with
4.1.2 to break on 4.3.4?
Have you verified that you have in fact updated gcc from one version
to another with an incompatible ABI?
Since the GCC upgrade guide doesn't mention a way to do this, no, I
haven't... so how does one verify this, Obi-Wan? ;)
Understand what the gcc upgrade guide is:
a quick simple guide for user who don't know tool chains inside out, that give
the minimal sequence of commands that is GUARANTEED to NOT leave the user in
the lurch. It's not the minimum possible sequence of commands to do the
upgrade, because most users don't know how to tell the difference. Here's the
logic:
If we imply that you should merge -e world with a gcc upgrade, my inbox will
not fill with bugs from users who don't know the inner guts of the toolchain.
The Guide is not the best possible guide that can be. It is the guide that
causes the least support questions from users.
There is a false idea floating about that gcc updates require
updating -e world.
This is not true.
I've heard this before, but could never get a definitive answer on how
to know for sure when you do and don't need to...
When the gcc devs release a new version, they will announce that there is an
ABI break, and what it applies to. It doesn't happen often, but when it does,
the gentoo maintainer ought to put a note in the ebuild.
They are quite diligent about this, much like the KDE/Qt devs do the same
thing when Nokia breaks Qt compatibility.

separate/individual logs ion /var/log/portage/elog, but what I'm

[gentoo-user] custom package make options?
Hello, I've got a box with two processors so i have MAKEOPTS set to -j2. One package gnome breaks during compile under these circumstances so am wanting to install it and only it with MAKEOPTS set to -j1 i'm thinking i have to put a file somewhere to pass custom make options to emerge gnome, but not sure where.

[gentoo-user] How to use X configure or driver from Ubuntu
Dear all, I use a Compaq 7550 monitor. It's a CRT. Currently, I can not adjust the refresh rate under Gentoo, but it was adjustable when it was running Ubuntu.

[gentoo-user] I want my Ctrl+Alt+Backspace back
I've seen on this group some time back a few ways, or at least more
than 1 as I recall to retain the ability to leave X with
Ctrl+Alt_+BKSPC.
I'm not finding it now readily.
Can someone tell me where that setting may be made.
If it has something to do with new way of starting X where we don't
need an xorg.conf file... I should say that I still use
/etc/X11/xorg.conf (In case that makes a difference)
I find trying to leave X with the `logout' menu item provided on the
Xfce4 destop, that if X has been running a while is seems to take a
very long time to get out of X that way, and possibly not only long
but even ever, short of:
kill -TERM `ps wwaux|awk '/X.*\-nolisten tc[p]/{print $2}'`
Or killing the pid some other way.
The Ctrl+alt+bkspc was a much nicer fallback.

Using multiple RAID partitions without LVM is far to complicated for my brain to handle. -- Neil Bothwick Nahh...I don't believe that for a moment, but this is a rather more complicated task than a basic desktop PC. This is about number crunching using multiple instances of Windows running under VMWare. First, the basic system: /dev/md3 - 50GB 3-drive RAID1 = The ~amd64 install we discussed over the last week. This is the whole Gentoo install. /dev/md5 - 50GB 3-drive RAID1 = A standard stable install - same as md3 but stable, and again the whole Gentoo install. Obviously I don't use the two above at the same time. I'm mostly on stable and testing out ~amd64 right now. I use one or the other. /dev/md11 = 100GB RAID0 - This partition is the main data storage for the 5 Windows VMs I want to run at the same time. I went RAID0 because my Windows apps appear to need an aggregate disk bandwidth of about 150-200MB/Sec and I couldn't get that with RAID1. I'll see how well this works out over time. /dev/md6 = 250GB RAID1 used purely as backup for the RAID0 which is backed up daily, although right now not automatically. The RAID0 and backup RAID1 need to be available whether I'm booting stable (md5) or ~amd64. (md3) I found some BIOS options, one of which was as default set to 'Fast Boot'. I disabled that, slowing down boot and hopefully allowing far more time to get the drives online more reliably. So far I've powered off and rebooted 5 or 6 times. Each time the system has come up clean. That's a first. I could maybe post a photo of what I'm seeing at boot but essentially the boot process complains with red exclamation marks about md6 md11 but in dmesg the only thing I find is the one-liner md: created md3 md: bindsda3 md: bindsdc3 md: bindsdb3 md: running: sdb3sdc3sda3 raid1: raid set md3 active with 3 out of 3 mirrors md3: detected capacity change from 0 to 53694562304 md: ... autorun DONE. md5: unknown partition table and after that no other messages. BTW - I did sort of take a gamble and change the partitions for md6 and md11 to type 83 instead of 0xfd. It doesn't appear to have caused any problems and I have only the above 'unknown partition table' message.

[gentoo-user] Where's my wireless AP?
Last night I was connected wirelessly to my access point and all worked fine. Well, towards the end the connection was bobbing up and down as far as my unreliable broadcom NIC is concerned (nothing wrong with the router). I decided to shut it down and go to bed. Today the AP is just not there! Not there as far as this stupid broadcom wireless NIC is concerned. The same machine booted into MSWindows has no problem seeing the AP and associating with it. Another laptop can also see the AP and connect to it. How come the broadcom cannot see it in Gentoo, but it can see all the neighbours APs which have a much weaker signal and even associate and get an IP address from one of them?! I am lost as to what might be causing this. Could it be some lock file that was not removed when the machine is rebooted or the wlan0 interface taken down? Any ideas how I can troubleshoot this? -- Regards, Mick signature.asc Description: This is a digitally signed message part.

Cell phone data plans are exorbitantly expensive, the telcos and cablecos are *REDUCING* monthly gigabyte allowances, cable/satellite is rather expensive, and we've never had unencrypted QAM HDTV channels. Just be aware of what you might be up against, and if it doesn't matter then enjoy the HDHR because it's a great little product. Given the cost of cable, especially HDTV, I'm strictly OTA. Toronto is an exception to the regular Canadian OTA TV scene. All but one of the local stations is already broadcasting digital, and I can get them and most of the Buffalo stations with an indoor antenna. It helps that I'm in a 6th floor condo with a clear view to the CN Tower (Toronto locals) and Grand Island, New York (the Buffalo TV antenna farm). Plus I get a news+movies station out of Hamilton. The total is 16 physical digital channels and 3 non-duplicate sub-channels. And coming soon is TheCoolTV http://www.thecooltv.com/ The list at http://www.thecooltv.com/THECOOLTV_SinclairTelevisionGroup.php shows Buffalo as one of the Cities About to Get COOL!. The rollout is due sometime in April or May. It'll be a sub-channel on one of the 2 Sinclair stations in Buffalo (WUTV-FOX or WNYO-MyTV). There's also one educational channel here in Toronto that is still analogue-only, which the HDHomerun can't get. They'll flash-cut to digital at the deadline. Canada's analogue shutdown is August 31, 2011, assuming no delays. -- Walter Dnes waltd...@waltdnes.org

Since mailing list users generally use threaded messages, please start a new message instead of replying to a old one. This may not be a bug. It depends on how you set your clock. You need to check the settings in /etc/conf.d/clock and make sure you have it set up correctly.

/dev/sda:
setting Advanced Power Management level to 0xfe (254)
HDIO_DRIVE_CMD failed: Input/output error
HDIO_DRIVE_CMD(identify) failed: Input/output error
gandalf linux #
hdparm does work though:
gandalf linux # hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 11552 MB in 2.00 seconds = 5779.10 MB/sec
Timing buffered disk reads: 314 MB in 3.00 seconds = 104.50 MB/sec

Thanks,

It seems that this possibly doesn't APM...

Re: [gentoo-user] Are runlevels 3 4 5 the same?
On Sun, 18 Apr 2010 23:58:17 +0100, Peter Humphrey wrote: That's whay I used to do until I found the gentoo=nox option, it saves maintaining an extra runlevel. But X isn't the only thing I don't run when not running X, if you see what I mean. Only about 3 other things differ at the moment, but I leave the possibilities open. In that case, another level is a better option. And I don't have to type anything at the grub command prompt. Of course not, you have an extra GRUB menu option to specify the runlevel, as I do to specify the nox option. And maintaining the other run level is not arduous anyway, as changes occur only when I install or remove a system service. Rarely, in other words. I used a script in local.stop to copy all symlinks in default to the nox runlevel, except the ones I didn't want to run, which were only xdm and vmware, hence my preference for the simpler soluton when it bacame available. To each his own, of course, as ever. Indeed, choice is wonderful. -- Neil Bothwick Uhura: Captain, you're being flamed on channel one. signature.asc Description: PGP signature

dan blum wrote: Dale, Thanks for following up. HOw do you start a new thread? It is slightly annoying when you change a setting and reverts back to the original; the whole (computer) system should be more user friendly. Either way, it is good that there is an easy fix, which I will do. I will have much more complex issues to discuss shortly. Thanks. You started a new thread with this one. ;-) It really depends on your email program. Mine, I can just chose to compose a new message and type in the email address. I can also right click on the email address, usually from another message, and then select 'Compose New Mail' to and it starts a shiney new thread. Tell us what you are using and I'm sure someone here uses it and can tell you more specifics on how to start a new thread. Questions about your setup. Do you dual boot windows? Do you dual boot another OS, even Linux? Is Linux the only OS you have installed? I only have one OS that I boot here so my settings will be different from yours if you dual boot something else. We need more info first tho. Also, can you give a little info about how the clock is set in your BIOS? This is really needed if you are dual booting. Dale :-) :-)
