[gentoo-user] Does anyone have Gentoo running on a ThinkPad x13 AMD (Ryzen 7 Pro 6850U)?
I've re-loaded stage3 adm64 tarballs for a few weeks, keep failing due to SIGILL running tar & bzip2. If I build the tools by hand the seem to work. At this point I've tried installing from stage3-amd64-openrc-20230521T160357Z.tar.xz and the prior three builds. Looking to get a copy of a working /usr/src/linux/.config file and any information on kwikhaks to get around the install issues.

No, but the previous version was working without it.

The other packages on the system get installed in the root after
being collected in the temp dir. I cannot find this package
getting installed anywhere further:
>>> Completed installing app-emulation/virt-manager-4.0.0

qlist shows some files in /usr/share, look left over from the
previous install. The only remaining executables are:
/usr/bin/virt-xml
/usr/bin/virt-install
/usr/bin/virt-clone
notice the lack of virt-manager.

First time I've ever seen a package install into PORTAGE_TMPDIR... Q: What am I missing? The rest of last nights "emerge --update" went into places like /usr/bin... where you'd expect.

# emerge --info <https://pastebin.com/M54kvhg1> I spend more time maintaining a language I don't actually use lately... Emerge fails becuase python-exec-2.2 doesn't have its expected Pytnon version.

You are probably right: I've spent more time playing with PYTHON*TARGET variables and succesive rebuilds on this machine than actually doing any work for about a year. Annoyance is that I don't do anything else with Python here so it's only for the package manager. This is for a fresh build from a recent stage3.

[gentoo-user] Q: What is "python-exec2c"? Why would "python3" dispatched through it not see an installed copy of pyyaml?
Question then is why "python-exec2c" dispatched via a symlink from "python3" would fail to see the installed copy of pyyaml (or how should I check with modules are avalable via "python3")? e.g., is there the equivalent of "perl -MYAML -d -E 0" that would allow me to check what it is that python thinks is installed?

This system has been fried ever since
2020-04-22-python3-7
Title Python 3.7 to become the default target
AuthorMichał Górny
Posted2020-04-22
Revision 1
On 2020-05-06 (or later), Python 3.7 will replace Python 3.6 as one
of the default Python targets for Gentoo systems. The new default
values will be:
Followed those instructions -- don't use python for anything here
and the local copies of what I actually use are in /opt/perl,
/opt/postgresql, etc, built from git checkouts.
At this point I've added and removed python single and multiple
target entries from make.conf & package.use/local, with various
sets of values and exclusions.
A bare sync tells me there is a new version of portage available,
installing it fails, however with:
# emerge --sync;
Action: sync for repo: gentoo, returned code = 0
* An update to portage is available. It is _highly_ recommended
* that you update portage now, before any other packages are updated.
* To update portage, run 'emerge --oneshot sys-apps/portage' now.
# emerge --oneshot sys-apps/portage 2>&1 | tee a;
Calculating dependencies ... done!

Re: [gentoo-user] Going through these one by one.
You've made the mistake of appearing knowlegable :-)
20 years I've been using Gentoo, I'm about to remove it because I
have not been able to maintain it since the whole python 2.7
deprecation process started.
Given my /usr/portage/package.accept_keywords is down to a
single line:
*/* ~amd64
At this point pretty much anything I try to update bumps into:
I have tried various combinations in package.use/local (i.e.,
separate from zz_autoconfig) of:
nada.
*/* PYTHON_TARGETS="-python2_7"
*/* PYTHON_SINGLE_TARGET="python3_6"
*/* PYTHON_TARGETS="-python2_7 python3_6"
*/* PYTHON_SINGLE_TARGET="python3_6"
followed by a combinatorial product of -python2_7 python3_{456789}
for the PYTHON_TARGETS and each of the alternatives as PYTHON_SINGLE_TARGET.
I've tried setting these in /etc/portage/make.conf also.
One oddity I notice is that emerge and eselect seem out of sync on
the version of python installed:
# eselect python list;
Available Python interpreters, in order of preference:
?[1] python3.7
?[2] python3.6
?[3] python2.7 (fallback)

Q: If you have a working Gentoo system, what version of python do
you have installed? What does eselect show you? What are you
using for PYTHON_TARGETS & PYTHON_TARGETS?
Thank you.

After conversion to elogind I cannot start X11. I've re-emerged PAM, though the ._cfg_system-auth tried to remove elogind.so, oddly enough. At this point my Xorg.0.log includes: systemd-elogind: Logind integration requires -keeptty and -keeptty was not provided, disabling elogind integration. Looking for -keeptty I find: <https://bugs.gentoo.org/599470> I found 74 packages installed on my system with at least one systemd reference in them. Most only install service files. Some make use of systemd-journal. Only 10 make use of libsystemd-login, and I have now submitted all of them but x11-base/xorg-server. The latter has to be started with "-keeptty" to add systemd-login/elogind integration, and that argument is strictly for debugging.

[gentoo-user] X11 fails to start up after elogind emerge
Starting with:
<2020-04-14 Desktop profile switching USE default to elogind>
<https://www.gentoo.org/support/news-items/2020-06-24-xorg-server-dropping-default-suid.html>
I've updated my USE with:
elogind -consolekit -systemd
Did an "emerge --update --changed-use @world", rebooted, logged
in, had problems starting X11, did an "emerge @x11-module-rebuild",
reboot, login, failed starting X11, did an "emerge @world" [which
succeeded, strangely enough], reboot, login, failed starting X11.
At this point I reboot, log in and validate the elogind but get:
$ logincel user-status;
Could not get properties: Is a directory
Using strace shows the last open was looking at /proc/self/stat,
which most definately is a file. The last thing logind was doing
is a ppoll & recvmsg with the nastygram:
<https://pastebin.com/vZzWCHKL>
Another thing is that using "startx", Xorg.log includes the line:
systemd-logind: logind integration requires -keeptty and
-keeptty was not provided, disabling logind integration.
Not sure if this is related to the properties error or something
else blowing up.
emerge --info:
<https://pastebin.com/Y0FVLLve>
emerge --verbose --info:
<https://pastebin.com/LDfH4wz5>
Running startx as SU does not solve the issue, the user is already
in tty and input groups (i.e., has access to /dev/tty* and
/dev/input/{event,mouse}*).
Q: Any suggestions on what I might do to get X11 starting again?

The Perl community has had CPAN::Reporter for a while and a set of smoke-test machines that run it. Normal Perl installs run "make test" as part of the normal install, the reporter feeds back test results to the authors -- I get a daily report of what failed and where. The smoke-test servers run CPAN::Reporter on whatever gets checked in each day. In today's world it's rather easy to set this up with docker, using Gentoo and some temp volumes (e.g., example using Gentoo for smoke- testing CPAN: https://www.slideshare.net/lembark/smoking-docker). Adding a Reporter-ish layer to a new version of Portage or a smoke- testing option that does a "emerge --install" into a temp layer in Docker, reports the outcome, and discards the results shouldn't be all that hard.

Once you have a source-based distro the package manager can be a matter of choice also -- so long as it accepts the existing package constructs as input. As pointed out earlier, Gentoo hasn't forked often, it's configurable enough that noone needs to fork it to have the results meet their needs. Pretty much the only thing we all have to have in common is the portage source packages; after that there could easily be mutliple installers.

Might give some better error messages -- it's also a nice package, worth a few bucks to have something that Just Works and also helps support someone who actually releases software for Linux. Depending on which syslogger you use, create /var/log/debug with debug-level output (no idea how to do this with systemd), zero the log, and tail -f it while you plug in the scanner, try to use it.

Re: [gentoo-user] Re: grub-2 update
Solution that works for me:
- Compile the kernel with everything built-in leaving modules for the
few things that really need to be reloadable. Turn everything in
the bloody thing off. This avoids the need for a kernel-specific
filestem in the initrd.
- This since you don't need any modules in the initrd a
simple, static solution with busybox and init something
like:
#!/bin/busybox sh
/bin/busybox --install -s;
sync;
mount -t proc none /proc;
mount -t sysfs none /sys;
/sbin/mdadm --verbose --assemble --scan;
/sbin/vgscan--verbose;
/sbin/vgchange --verbose -a y /dev/vg00/root;
mount /dev/vg00/root /mnt/root;
mount;
exec /sbin/switch_root /mnt/root /sbin/init;
Add whatever you need for encryped filesytems, but it
won't have to change over time unless you change the
boot requirements.
Add a copy of busybox, switch_root, init, a static copy of lvm
into something like /boot/standard-init.cpio.gz. Mine is in
/usr/src/initrd with two sub's standard and rescue differing
only in the init script. A second initrd the last line commented
out as /boot/rescue-init.cpio.gz for cases where switch_root gets
unhappy.
#!/bin/bash --login
cd $(dirname $0);
for i in */init;
do
dir=$(dirname $i);
name=$(basename $dir);
(
cd $dir;
kleenfilz;
find . |
cpio -o -Hnewc |
gzip -9v /boot/$name.cpio.gz)
done
wait;
ls -lt /boot;
exit 0;
builds and installs the initrd's easily enough (kleenfilz
is a shell sub that removes editor cruft, no reason to leave
*~ files :-).
- Add /etc/grub.d/09_custom (i.e., into the config *before* the
junk that 10 adds in) like the one below. Note that this uses
the symlink /boot/vmlinuz with the static init. The current
portion comes from a second vmlinuz.stable symlink I curate
manually to the last kernel that lived for a while and never,
ever caused problems [not that I've ever botched a config
siwtch. no, really...].
The standard link and fixed init-script allow a static copy of the
grub config file with /boot/vmlinuz and /boot/standard.cpio.gz
hardwired.

After that you can get a Smart UPS, which is basically a line conditioner and a battery in one box. This solves your flicker problems. A Smart-UPS 750 will probably handle anything you need for a desktop and L[CE]D screen, for two of them you can get a 1.5KVA that will give you plenty of time for shutdown even with two machines. For a home unit, your best bet is to size the thing for a reasonable shutdown period rather than try to keep everything running through a potential blackout. Reboots don't take that long and the cost+overhead of running an oversize unit adds up. You have a different calculation for servers or racks, where uptime is more of an issue.

Re: [gentoo-user] umask 002 in /etc/profile
What with usergroups being the default behavior, do you think it's quite reasonable to use 002 as a default umask? Most group-sharing use-cases I've encountered have people that are sharing groups share files as read-write anyways, and by default, users have their own private group which nobody else is a member of; i.e. g+rw still won't allow others to write them. That was the idea, RH did it that way a dozen years ago for exactly the reason you mention: dir mods of 02770 make it easy to share files but require 002 umask. Fix was to set the per-user group, allowing private dir's (largely $HOME) to have tighter mods with files below them group readable by a single-user group. The scheme works rather nicely in nearly every situation (POSIX ACL's play hell with the scheme, but, then, they are supposed to). enjoi -- Steven Lembark85-09 90th St. Workhorse Computing Woodhaven, NY, 11421 lemb...@wrkhors.com +1 888 359 3508

Re: [gentoo-user] Gentoo's advantage: optimized for your system -- huh?
Where did that bit of apocrypha come from, and why is it parroted by so many people? snip Depending on what you do with the system it still can be quite true. For example, there is a known bug in the RH distro of Perl that leaves it running 10x slower than a locally compiled version. There are also quite a few packages that still come compiled with '-g', or depend on 15 shared object lib's that you don't use but now cannot turn off. If you are trying to squeeze performance out of a box then any kind of cruft will slow you down. You can also look at library-dependency hell as a form of performance hit: if you spend X hours trying to work around the library glitches it's that much dead time on the box you aren't using. -- Steven Lembark85-09 90th St. Workhorse Computing Woodhaven, NY, 11421 lemb...@wrkhors.com +1 888 359 3508
Re: [gentoo-user] Tips/Tricks for Gentoo on low-spec computer?
I'm in the process of installing Gentoo on a rather old machine. It's an old HP Pavilion with a 450MHz Celeron Mendocino and 256MB of PC133 SDRAM. I'm using an nVidia PCI FX6200 video board instead of the i810 on-board chip, and it's got a decent hard drive (160GB). I was wondering if there were any particular tips/tricks for getting the best performance out of such a machine. It's to be used for basic word processing and a few games. Hopefully the nVidia 6200 will allow OpenGL to run fast enough for something like TuxRacer. I chose XFCE for the desktop along with both Abiword and OpenOffice. I probably should have installed OOo from a binary package, but I decided to build it just to see how long it would take (so far it's at about 26 hours and counting). Fvwm is lightweight. Make a point of compiling the kernel without anything you don't need; if you might need something then make it a module. Don't run daemon's you don't really need. For example, log into the command line and use startx or xinit rather than having the thing boot into an X11 login. Use a large amount of swap compared to ram (with your drive maybe 2G) and avoid tmpfs for working storage. If all you're using the thing for is surfing or basic development then it should work fine. The old standard for using X11 was a minimum 12MB of core and 40MB disk. For a long time that was difficult, then IDE came along and big disks got cheaper :-) -- Steven Lembark85-09 90th St. Workhorse Computing Woodhaven, NY, 11421 lemb...@wrkhors.com +1 888 359 3508

Re: [gentoo-user] Emergency shutdown, how to?
Main thing that speeds up the AMD box is using 320MB scsi's for near-term storage. They are hugely faster than [S]ATA or IDE used on most equipment these days. what R/W speeds can you expect? Operations on SCSI run 2-3 times faster for large-ish file transfers (say 1MB or more). For example GIMP runs without noticeable pauses on most operations with my 2GHz opteron using the SCSI's as storage and scratch space; on the same machine with the SATA's it bogs down to the point of annoyance, with things like saves taking seconds to complete. The only difference being which drives I'm using for tiles and data. Bonnie gets upset validating the scsi space on this box since it has 8GB of core and I don't have 16GB free on the device so I can't give you any specific numbers. -- Steven Lembark85-09 90th St. Workhorse Computing Woodhaven, NY, 11421 [EMAIL PROTECTED] +1 888 359 3508 -- gentoo-user@lists.gentoo.org mailing list

Then there is all the other services that have to stop. Quite literally, I only had seconds to shutdown since the P/S was stinking like a skunk. I just needed to umnount the file systems and power off as fast as possible. I didn't want to just pull the plug but I needed a shutdown that fast. Hackint the shutdowns to background the shutdown op and return is usually pretty simple -- don't know why more app's don't do that by default. 'halt' will get you down with little typing if you want to bypass the init scripts; so will kill -TERM 1. Add a 'sync' before either of them and you'll probably be able to come up with minimal trouble. What's the difference between halt command and shutdown? I thought they were basically the same thing. Also, in case you missed it. I have a service, foldingathome, that takes a while to stop and no other service can be stopped in parallel with this one. That is one of my key sticking points with the shutdown. Most of the others are pretty fast. I just needed the quickest *clean* shutdown I could get. Thanks I have four FAH jobs running on my compute server. I can kill -TERM fah6 in about 0.70 sec here, they start up again and just keep going. FAH is pretty robust when it comes to restarts; again if you crash the proc's then it won't be any worse than the outcome of loosing power: FAH will have to pick up its pieces and keep going. At least with halt -f you'll get the kernel space cleaned up. Halt will stop the O/S (see note from manpage, below). In this case a 'halt -f' would get the system down about as quickly as possible without just hitting the reset button. NOTES Under older sysvinit releases , reboot and halt should never be called directly. From release 2.74 on halt and reboot invoke shutdown(8) if the system is not in runlevel 0 or 6.

I also learned that the halt -f -p command should be really fast if this happens again. Keep those thoughts coming. poweroff -f; NAME halt, reboot, poweroff - stop the system. SYNOPSIS /sbin/halt [-n] [-w] [-d] [-f] [-i] [-p] [-h] /sbin/reboot [-n] [-w] [-d] [-f] [-i] [-k] /sbin/poweroff [-n] [-w] [-d] [-f] [-i] [-h] -- Steven Lembark85-09 90th St. Workhorse Computing Woodhaven, NY, 11421 [EMAIL PROTECTED] +1 888 359 3508 -- gentoo-user@lists.gentoo.org mailing list
Re: [gentoo-user] Emergency shutdown, how to?
Basically, this is not intended to be used to shutdown a puter on a regular basis, unless you burn out P/S's on a daily basis. O-o Just didn't want someone to be using this on a regular basis and then wondering why their system has a new nickname, FUBAR. :'( In most cases you'll find that 'shutdown -h now' takes only a few seconds. If you're typing againsed the clock and don't to it every day then the SysReq tecnhique is somewhat error prone. In most cases the stuff that can't handle a crash tends to live at higher runlevels anyway and gets stopped when you exit rl 3; stuff that gets started at boot time are more likely service daemons that can easily handle a reset. Even if your shutdown croaks halfway through the stuff, chances are that got shut down first was the most fragile anyway (e.g., databases that had to flush cache) and you got whatever you could cleaned up however fast you could do it and you live with the rest on restart. -- Steven Lembark +1 888 359 3508 Workhorse Computing 85-09 90th St [EMAIL PROTECTED] Woodhaven, NY 11421 -- gentoo-user@lists.gentoo.org mailing list
Re: [gentoo-user] Emergency shutdown, how to?
Well, this one takes longer. Just the foldingathome takes about 20 seconds or more to shutdown. It can take over 60 seconds at times. That service for some reason has to completely shutdown before the others start to shutdown. The others will shutdown in parallel like I have set up. Then there is all the other services that have to stop. Quite literally, I only had seconds to shutdown since the P/S was stinking like a skunk. I just needed to umnount the file systems and power off as fast as possible. I didn't want to just pull the plug but I needed a shutdown that fast. Hackint the shutdowns to background the shutdown op and return is usually pretty simple -- don't know why more app's don't do that by default. 'halt' will get you down with little typing if you want to bypass the init scripts; so will kill -TERM 1. Add a 'sync' before either of them and you'll probably be able to come up with minimal trouble. -- Steven Lembark +1 888 359 3508 Workhorse Computing 85-09 90th St [EMAIL PROTECTED] Woodhaven, NY 11421 -- gentoo-user@lists.gentoo.org mailing list

Since I wanted to shutdown instead of reboot, it would be ALT + SysRq + S + U + O then correct? Are there any potential harms to the hardware / system in case one tends to abuse (i.e. use more often than necessary) of this command? It's so often so tempting to shut down your system fast. Short of a serious emergency (e.g., UPS with 30-sec lag and no input power) stick with 'shutdown -fh now'. The main problem is that you bypass the stop phase of all the app's started up via init.d; very little short of just hitting the reset switch or yanking the power. -- Steven Lembark +1 888 359 3508 Workhorse Computing 85-09 90th St [EMAIL PROTECTED] Woodhaven, NY 11421 -- gentoo-user@lists.gentoo.org mailing list
Re: [gentoo-user] Clone a running gentoo machine onto another machine
Now, correct me if I'm wrong, but I had read that if you don't copy the files in /dev, udev won't mount properly on the machine you're cloning to and all hell will break lose. Also, iirc, I believe I tarred a running machine (including /dev, excluding /sys) and the clone was successful. Any thoughts? One other way: mirror the boot/root/install devices (maybe a single partition). You can make, sync, and drop the mirror, install grub on the new mbr and have a clone of the system (basically you'd be in the same situaiton as if the primary drive of a mirrored setup croaked). -- Steven Lembark +1 888 359 3508 Workhorse Computing 85-09 90th St [EMAIL PROTECTED] Woodhaven, NY 11421 -- gentoo-user@lists.gentoo.org mailing list

Re: [gentoo-user] Recovering root password
I am starting to wonder why am I so attached to my root password being strong.. :) Becuase I can crack a simple password from outside of the box. Hacking in w/ a CD or the init=blah approach requires physical access and a reboot, both of which are fairly noticable and preventable. -- Steven Lembark +1 888 359 3508 Workhorse Computing 85-09 90th St [EMAIL PROTECTED] Woodhaven, NY 11421 -- gentoo-user@lists.gentoo.org mailing list
Re: [gentoo-user] Recovering root password
If it is possible to have sufficient access to be able to remove the hard drive, then an encrypted filesystem is essential. Any computer that isn't nailed down behind a locked door should have this, unless it contains and has access to absolutely nothing of value. Which setup does anyone out there use for the encfs? -- Steven Lembark +1 888 359 3508 Workhorse Computing 85-09 90th St [EMAIL PROTECTED] Woodhaven, NY 11421 -- gentoo-user@lists.gentoo.org mailing list
Re: [gentoo-user] Recovering root password
them. Things have indeed changed since 1978 Unless you include the time in 1972 that some of my friends broke into the computer room, hacked the PDP-11, and inserted Panther, Pink into every class in the highschool. They have remained hugely the same :-) -- Steven Lembark +1 888 359 3508 Workhorse Computing 85-09 90th St [EMAIL PROTECTED] Woodhaven, NY 11421 -- gentoo-user@lists.gentoo.org mailing list
Re: [gentoo-user] Recovering root password
On the grub menu, edit the entry of the system you want to boot and on the kernel line, add init=/bin/bash without the quotes. Boot that modded boot instructions sequence. After kernel loads, you'll have a bash. Type: mount -o rw,remount / Make sure that your bash is statically linked, otherwise you can run into problems with this approach. It's acutally a good idea to keep a static bash and just put this into grub as the 'shell-init' or 'rgh' entry (it's in their example config). -- Steven Lembark +1 888 359 3508 Workhorse Computing 85-09 90th St [EMAIL PROTECTED] Woodhaven, NY 11421 -- gentoo-user@lists.gentoo.org mailing list
Re: [gentoo-user] Recovering root password
It's probably better to use a shell designed for rescue work, like sash or busybox instead of bash, especially if /usr is on a separate filesystem. The statically linked bash acutally works rather well for this. The main advantage I've found using it for recovery situations is that I'm used to it: sourceing root's .bash_profile is enough to give a familiar environment. -- Steven Lembark +1 888 359 3508 Workhorse Computing 85-09 90th St [EMAIL PROTECTED] Woodhaven, NY 11421 -- gentoo-user@lists.gentoo.org mailing list
