yes, you can disable the external servers. if the systems are running on
the same LAN (same VPN could work too?) they should find each other
nevertheless. or you could host your own discovery/relay server
somewhere.

are you sure it's all because of dev-cpp/abseil-cpp? according to the
log[1] it was prematurely stabilized a few days ago and reverted
2023-10-17. that could explain 2 of the last 3 app-office/libreoffice
rebuilds. however, i don't see anything matching the other rebuilds. i
haven't checked masks though, maybe some versions of abseil were masked
for a while?

most likely you didn't define PORTAGE_LOGDIR in your make.conf and it's
empty by default (check with `portageq envvar PORTAGE_LOGDIR`).

well, you need to have a backup, of course. with ext4 it can happen that
a file is corrupted in a way that is not immediately obvious but causes
further damage down the line. or you get artifacts in your music and
only notice it after it is too late and all your backups have the
damaged version.

it'll use more cpu and memory, but disk writes and reads will be lower,
because it compresses it on the fly. it should detect early if a file
is not compressible and stop. it's also possible (with btrfs at least)
to enable it on a directory basis.

btrfs and zfs have some useful features for normal use cases. the
transparent compression can save a lot of space and even increase speed
in some cases, the checksumming guarantees that you will never get a
corrupt file and snapshots make backups and rollbacks easier.

however, they do need a bit more maintenance (described in their
respective wiki articles).

you can send snapshots to other drives or computers, either as full or
incremental backups. i'd say it's pretty much the same. 

Yes, you can just continue to use them. The ebuild will be kept in
/var/db/pkg/ in case portage needs to reinstall them or so.
However, it might make sense to copy it to a local overlay to make it
easier to get an overview of self/un -maintained packages. And since
gsutil requires Python, you'll have to modify the ebuild at some point
anyway to add support for newer Python versions.

I'd say use the ebuild since it already exists. Makes breakage less
likely.

I don't know if it changed recently, but the current ebuild removes
"${ED}/usr/bin/virt-manager" (in pkg_preinst()) if the gtk USE-flag is
not enabled.

Do you have the gtk USE-flag on app-emulation/virt-manager? Does
`qlist app-emulation/virt-manager` show installed files?

That is normal. it is installed into ${PORTAGE_TMPDIR} and then merged
into ${EROOT}/ to make it less likely that the filesystem is getting
messed up.

I use mail-client/claws-mail, with the dillo plugin to view the
occasional HTML only email. It apparently also has a webkit plugin, in
case you get “extra fancy” mails.

claws-mail is pretty lightweight, very configurable, can spawn an

/usr/bin/test[1] was installed by sys-apps/coreutils[2], it's homepage

[gentoo-user] Remove codepoints from fonts with fontconfig

[tastytea]

Hi,
i added a colour emoji font as my last preferred font to fontconfig and
want to get all emojis from it. The problem is, that my first preferred
font contains some mono coloured emojis that override the colour emoji
font. This is my config:

  
monospace

  Source Code Pro
  Source Han Mono
  Noto Color Emoji

  

and the same for serif and sans-serif[1].

I tried to “remove” the offending codepoints from all fonts matching
*Source* like this:

  

  Source


  
charset

  0x2764 
  0x1f916 

  

  

but that only works partially. After running `fc-cache -f` the emojis
are shown correctly in xfce4-terminal and GTK 2/3 programs but not in
alacritty and Qt5 programs. Firefox gets only some of them right.
Rebooting didn't help.

Is there a way to make it work everywhere?

Network access is disabled in ebuild phase functions by
FEATURES="network-sandbox". You can disable that by adding
RESTRICT="network-sandbox"
to your ebuild, but it's better to fix the build script instead.

Judging by the git log[1] and `eshowkw sys-kernel/gentoo-sources`[2], it
looks like it was part of a cleanup, a lot of old kernels were dropped.
5.15.59 presumably wasn't dropped because it's the latest stable on
hppa. I guess the other arches were unkeyworded to keep the list of
supported kernels somewhat reasonable.

Yes, /etc/init.d/mount-ro will take care of that. It first calls `sync`
and then calls `umount -r` on everything. It's set up to ruin on
shutdown by default. I'm sure systemd does something similar.

I don't think `cryptsetup luksClose` is necessary on shutdown, since it
only sets up the mapping(?).

It's not bad at all if you use a distribution with a better default
configuration, pre-installed drivers and a pre-installed GUI for setting
up the automatically detected printer in less than 5 clicks.
Unless you have a printer from a shitty company, of course.

Since the grub boot menu includes all kernels in /boot by default as
far as i know, it is probably necessary to run eclean-kernel with
--destructive and re-generate the boot menu afterwards.

I'm not familiar with nodejs in particular, but dropping the debug
USE-flag will probably reduce the amount of memory it needs somewhat.

It probably reinitialises PATH when dropping to the portage user? Try
modifying PATH in /etc/portage/bashrc — note that this file is sourced
multiple times during the build, see

It is on its way out, but there are still some packages blocking its

guess GTK+ 2 will stay at least another few months.

I don't know why it is doing that or how to fix it, but the strange code
is a unicode code point. You can enter it in many terminal emulators by
pressing Control + Shift + u and then 20ac + Enter or display it with
echo "\u20ac".

Most providers just use the virtualization that is built into the Linux
kernel, the same QEMU/KVM that you can setup yourself with libvirt. You
need to select some VIRTIO drivers but that's about the only difference
to a “normal” system. As far as I know sys-kernel/gentoo-kernel{,-bin}
has everything needed built in.

If the platform offers you access to the VGA output via VNC or whatever
and lets you mount an ISO in a virtual DVD drive, it pretty much works
like any other Gentoo install.

Another option is to shrink your filesystem and partition, make a new
partition and install Gentoo from the old install.

You could also try to make Grub boot into an ISO in your /boot
partition. If you don't have access to the VGA output, you could try to
find a ISO that starts an SSH server automatically and lets you set the
password via the kernel cmdline.

This tells you that dev-libs/gtkd needs at least one of (any-of) the
listed USE flags. You can enable USE flags in
/etc/portage/package.use¹. For example, to enable gdc-11_2_0:

echo 'dev-libs/gtkd gdc-11_2_0' >> /etc/portage/package.use/dlang

3.0.31 is only required for the new format (GPKG). Binary packages are

It is safer to copy the world file to /etc/portage/sets/¹ and then
emerge the set. This way portage won't think that the packages are
already installed. So you could copy it to
/etc/portage/sets/minimal-install and install it with emerge -a
@minimal-install.

ICANN rejected .home as a TLD¹ because of name collision issues in
private networks, so that should be fine.

Another solution would be to register an inexpensive domain name and use
that. 

You need to enable them explicitly. If you're using PAM:

It only has an effect after your next login. For more information, see

Hmm, I'm pretty sure this worked a few years ago. I just tested it on a
system on which I didn't configure mail before. My mails ended up in
/var/spool/nullmailer/queue. :-(

A lot of packages depend on virtual/mta, including mailx. It seems you
have no choice but to configure one of the MTAs virtual/mta depends on.

mail-client/mailx provides /usr/bin/mail which can be used for looking
at mail in /var/spool/mail/ and for sending it to local users. No
configuration necessary. cron and other software will automatically use
it.

It means the binary wants to load some libraries (like libexpat.so)
portage can't find.

But vmware (or rather, the linker) seems to find them. Maybe they are in
the same directory as the binary and portage doesn't search there? You
can check which libraries exactly the binary wants to load with ldd.

When you are connected via SSH, the environment variable SSH_CONNECTION
is set. I store the color in a variable and set it to yellow if 
`[[ -n "${SSH_CONNECTION}" ]]`. I can't give you the exact snippet
since I use Zsh, but it should be possible to use a variable as color

If the partition table is GPT (instead of msdos compatible), you can
set a label to the partition itself with gparted (right click →
name partition) and then access it via /dev/disk/by-partlabel/. That
works for encrypted partitions too, since the name is stored in the
partition table and not the file system.

I don't think it is possible to get consistent sd* names for removable
media. But you could use volume labels with `tune2fs -L` or `tune.exfat
-L` or `fatlabel` and then mount them via /dev/disk/by-label/*.

The name switch is announced via a warning message when you emerge udev:

WARN: postinst

udev-249 defaults to predictable interface renaming, as described in
the URL below:
https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames

If you wish to disable this, please see the above documentation, or set
net.ifnames=0 on the kernel command line.

You can change settings for log messages in make.conf, see
/usr/share/portage/config/make.conf.example for documentation (search
for PORTAGE_ELOG). I have
PORTAGE_ELOG_SYSTEM="save echo:error,warn,log" in my make.conf. echo
means the messages are displayed again when emerge exits.

It's not really a bug, more a workaround for projects that haven't
switched yet. I thought it makes sense to let the ebuild add the
symlink since yt-dlp and youtube-dl can't be installed at the same time.

But ionen mentioned in the other reply¹, that

That looks like it does not use the program, but the python module
directly. You could try if symlinking
/usr/lib/python3.9/site-packages/yt_dlp to
/usr/lib/python3.9/site-packages/youtube_dl helps. Replace python3.9
with your version of course.
If that works, please file a bug on bugs.gentoo.org.

yt-dlp already installs a wrapper script in /usr/bin/youtube-dl.

Google changed something to make youtube-dl slow and its development
seems to have stopped.

The fork everyone is using now is yt-dlp (net-misc/yt-dlp). It
downloads with normal speeds. The newest version of the ebuild installs
a compatibility-wrapper so programs calling youtube-dl will
automatically use yt-dlp instead.

Looks like some packages want python 3.8 and some python 3.9. If you

You need to run cmake in the directory that has the top-level

Maybe OpenRC should come pre-recorded into @world on profiles that
default to it. If I switch to another init system I can explicitly
uninstall OpenRC. Forgetting to uninstall it is no big deal.
Accidentally uninstalling it makes my system unbootable.

I'm not sure why it would want to remove openrc, as far as I know it
should be part of the @system set unless you're on a systemd profile.

You can record it in your @world set with `emerge --select --noreplace
sys-apps/openrc`. That should prevent accidental removals.

[gentoo-user] cgroups and OpenRC: Am I doing it wrong?

[tastytea]

www-apps/gitea often used all 4 of my CPU cores and slowed everything
else down. So I attempted to limit CPU usage with cgroups:

I have set this in /etc/rc.conf:

rc_cgroup_mode="unified"
rc_cgroup_controllers="cpu memory io pids"

And this in /etc/conf.d/gitea:

rc_cgroup_settings="
cpu.shares 128
cpu.cfs_period_us 100
cpu.cfs_quota_us  100
memory.limit_in_bytes 8G
"

According to my research, setting cpu.cfs_period_us and
cpu.cfs_quota_us to the same value should ensure that only the power of
one core is used, and “cpu.shares 128” should only use 12.5% (half a
core in my case) of the CPU if the system is under load. The CPU usage
in htop should be at most 100%, right?. However, I often see 110%,
sometimes up to 180% and rarely 230%. Are that all accounting errors or
did I do someting wrong? How can I check if my settings are applied?

Do you use a custom initrd? The kernel usually mounts / ro at first and
the initrd remounts it with `mount -o remount,rw /` later.
You can also mount / rw from the beginning by specifying “rw” instead of
“ro” on the kernel commandline¹. The current kernel commandline is
visible in /proc/cmdline.

The CPU will automatically throttle when a certain temperature is
reached. This may be the cause of the lockups.

Have you tried ondemand mode? It ramps up the speed faster than
conservative mode and drops equally fast if there is not much to do. I
have it enabled everywhere and didn't notice any problems.

As long as the website is find-able by search engines, it doesn't
matter if it is IPv4 or IPv6.
A good measure against non-targeted spam is a hidden input field with
the name “url”. If the bot put anything in that field, throw it out.
Simple math captchas (like “what is 2 + 3?”) work well too.
If the spam is targeted, you'll probably need a more advanced captcha
solution.

With the trailing slash it doesn't work, but
`tar -cvzf test.tar.gz --exclude="a/b" a` works.

That's because the files come last, the poster of the question has put
--exclude after the files.

When I'm in a, --exclude="./b" doesn't work, but --exclude="b" works.
tar doesn't seem to understand “./”.

This works fine here with “tar (GNU tar) 1.34”:

$ mkdir -p a/b
$ touch a/file a/b/file
$ touch a/file.xz a/b/file.xz
$ tree a
a
├── b
│   ├── file
│   └── file.xz
├── file
└── file.xz

1 directory, 4 files
$ tar -cvzf test.tar.gz --exclude="a/file" --exclude="a/b/*.xz" a
a/
a/file.xz
a/b/
a/b/file
$ tar -tf test.tar.gz
a/
a/file.xz
a/b/
a/b/file

You can find out the maximum length of the command-line with 
`getconf ARG_MAX`.

You could use zram[1], it's like a ramdisk but compressed. Source code
compresses very good, binary files compress to ~50% in my tests.

You could create /var/tmp/portage/dev-lang/rust after creating the
ramdisk and then bind-mount another directory to it. But then you'd
have to tell portage to not delete it with FEATURES="keepwork"[2]
(see`man 5 make.conf`) … I wouldn't recommend it.

The easiest solution would be to connect both machines with an ethernet
cable and run samba on Linux. The interfaces will be configured with a
link-local address¹ automatically.

If USB connections between the 2 machines are allowed then “IP
connection between the machines is not allowed” surely does not apply
to direct ethernet connections between the 2 machines?

That looks like you need to select the new ruby version with eselect.
It doesn't figure out the right version automatically, like python.

I'm not sure if the logs are stored by default, but if you set
PORTAGE_ELOG_SYSTEM="save" in make.conf, portage saves one log per
package in $PORTAGE_LOGDIR/elog. You can also have portage mail them to
you. See /usr/share/portage/config/make.conf.example for details.

There are also tools available to view these logs more comfortably:
app-portage/elogv and app-portage/elogviewer.

I did set it with eselect. pinentry works fine when I use gpg in the

[gentoo-user] pinentry doesn't work with Emacs anymore

[tastytea]

Hi!
A short while ago, pinentry-gtk2 was removed from
app-crypt/pinentry. Around the same time, app-crypt/gnupg was
updated. Since then, I can not use the gpg-agent from whithin Emacs
(--deamon) anymore. When I commit something with Magit, I get no
password dialog but this error message instead:

  error: gpg failed to sign the data

After I add the key to the agent in another way (with `echo "test" | gpg
--clearsign` for example), it works in Emacs again. So it seems that
there is something wrong with my pinentry setup.

I tried pinentry-gnome3 and pinentry-qt5, it makes no

You could install Gentoo into a directory without the build tools, but
you would have to install packages and update them from a full Gentoo
installation outside that directory. I've used that technique in my
Docker experiments.[1]

emerge --root=/workdir sys-apps/busybox will install busybox and all
build-time dependencies into /workdir.

In that case I'd recommend:
sudo FEATURES="keepwork keeptemp" emerge --resume
keepwork disables most of the clean phase.

ebuild(1) is useful for package maintainers to check if a package is
installing correctly and if the tests run successfully before pushing
it to a repository.

You could also use it to install packages that are not in a repository,
but I wouldn't recommend it.

Both the tinfo and the unicode use-flags are necessary if you need
libtinfow.so. From the ebuild:

if multilib_is_native_abi ; then
gen_usr_ldscript -a \
"${NCURSES_TARGETS[@]}" \
$(use tinfo && usex unicode 'tinfow' '') \
$(usev tinfo)
fi


Bash depends on readline. If readline was built with USE="unicode" it
depends on ncurses[unicode]. Try `chroot /mnt/gentoo /bin/busybox sh`.
Busybox doesn't depend on readline so that should work. However,
portage uses bash for ebuilds if I'm not mistaken. If you have a
computer with a compatible CPU and unicode disabled you could quickpkg
bash there and try to install it on the new computer. Or maybe copying
/bin/bash over is enough.

unicode is one of the useflags that are a real pain to disable after
install. :-(

It seems to be a bug in >=dev-python/urllib3-1.26.0.

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

The upgrade is not gonna be easy: <https://bugs.gentoo.org/710134#c2>.

There is a repo with mailman2 + dependencies, but that is only intended

--newuse and --changed-use are almost the same. The only difference is,
as far as I know:

--changed-use, -U
  […] Unlike --newuse, the --changed-use option does not trigger
  reinstallation when flags that the user has not enabled are added or
  removed.

I don't know why that didn't catch all python modules.

emerge --changed-use --deep @world should take care of that.

--changed-use updates packages where USE flags have changed since
installation and --deep makes emerge consider the entire dependency
tree of packages.

From what I could gather, opentmpfiles is only vulnerable when an
attacker is able to put a config file into /etc/tmpfiles.d/, so they
have to be already root.
Nevertheless I switched to systemd-tmpfiles and it just works and
doesn't pull any other systemd-stuff in.

I don't think it really matters which one you use.
