[gentoo-user] Problems with commands "reboot" and "shutdown"

[gentoo-user] Problems with commands "reboot" and "shutdown"

[Dr Rainer Woitok]

Greetings,

normally I just hibernate my laptop  and rarely reboot  or shut it down.
But after building kernel 6.6.58-1  I did of course reboot,  or rather I
tried,  because the laptop either stalled or went into an infinite loop.
Long pressing the power key did bring the system down, and switching the
laptop on again did bring it up, so I could at least investigate.

In syslog I found two suspect lines:

   Failed to execute /usr/bin/reboot: No such file or directory
   Failed to execute /usr/bin/poweroff: No such file or directory

If I'm not mistaken, these are the locations used by "systemd",  but I'm
running "openrc" which installs these two binaries into "/sbin/".   So I
created these two symbolic links in "/usr/bin/"  pointing into "/sbin/".
However, running "shutdown" still stalled or went into an infinite loop,
though without complaining in syslog about not finding "reboot" and "po-
weroff".

What eventually helped  on top of the two symbolic links  was rebuilding
package "sys-apps/openrc-0.54.2" with additional USE flag "+sysv-utils".
However,  I don't regard these additional two symbolic links  (which are
still required) as a real fix but rather as some sort of band-aid.

Mind that all this is not necessarily a problem with the new kernel ver-
sion.   It may just have surfaced now  because I wanted  to boot the new
kernel.   So, what am I missing?  Some news item?  Some new USE flag for
some package I have meanwhile installed or upgraded?   Some new configu-
ration variable in some configuration file?   Some new kernel parameter?
A bug?  I checked the list  of open bugs against "sys-apps/openrc",  but
was missing any sort of deja vu.

Any pointers appreciated.

Sincerely,
  Rainer

I'm on 6.6.58-gentoo-r1 compiled from gentoo-sources.  No systemd, only 
openrc.  This is what I have here:

~ $ ls -la /usr/bin/reboot 
lrwxrwxrwx 1 root root 4 May  2  2024 /usr/bin/reboot -> halt

~ $ ls -la /usr/bin/poweroff 
lrwxrwxrwx 1 root root 4 May  2  2024 /usr/bin/poweroff -> halt

~ $ ls -la /usr/bin/halt
-rwxr-xr-x 1 root root 22560 May  2  2024 /usr/bin/halt

I also have:

~ $ ls -la /usr/bin/halt.sh 
-rwxr-xr-x 1 root root 101 May  2  2024 /usr/bin/halt.sh

~ $ cat /usr/bin/halt.sh 
#!/bin/sh
if [ "${INIT_HALT}" = HALT ]; then
	exec /sbin/halt -dhn
else
	exec /sbin/poweroff -dhn
fi

Hope this helps.

/bin and /sbin should be symlinks to /usr/bin if you switched to profile

Hm, interesting.  What package does

   equery belongs /usr/bin/halt

return on your system and what USE flags do you use for that package?

I'm openrc here with a merged /usr setup.  Old rig is still split user. 
I could boot it up and get info if needed.  This is what I got on new
rig.  As you can see, I had to dig a little.  It's not where yours is
which may be a clue. 


root@Gentoo-1 / # equery belongs /usr/bin/halt
 * Searching for /usr/bin/halt ...
root@Gentoo-1 / # which halt
/sbin/halt
root@Gentoo-1 / # equery belongs /sbin/halt
 * Searching for /sbin/halt ...
sys-apps/sysvinit-3.09 (/sbin/halt)
root@Gentoo-1 / #


That help?

I'm on the same profile.  Wonder why Rainer shows something else??? 

I booted my old system, it has the same ruby issue I posted about
earlier so it needs fixing too.  This is what I get from my old system,
still on split usr.  I'm including reboot and shutdown as well.


root@fireball / # eselect profile show
Current /etc/make.profile symlink:
  default/linux/amd64/23.0/split-usr/desktop/plasma
root@fireball / # qfile halt
sys-apps/sysvinit: /sbin/halt
root@fireball / # qfile reboot
sys-apps/sysvinit: /sbin/reboot
root@fireball / # qfile shutdown
sys-apps/sysvinit: /sbin/shutdown
root@fireball / #


So, same package and location it seems.  Makes one wonder.  o_O

Same on my laptop:

   $ eselect profile show
   Current /etc/portage/make.profile symlink:
     default/linux/amd64/23.0/split-usr/desktop
   $ ls -l /sbin/reboot
   -rwxr-xr-x 1 root root 526 2024-11-08 10:14 /sbin/reboot
   $

Obviously the problem is somewhere else.  Meanwhile I found that running
"shutdown" directly from a shell  works without  the additional symbolic
links in directory "/usr/bin/".  But selecting "shutdown" or "reboot" in
Xfce's "Action Button"  popup menu fails  when these  symbolic links are
missing.

And I found that in syslog the message

   (3) reboo[14713]: Failed to execute /usr/bin/reboot: No such file or directory

is always immediately preceded (with exactly the same time stamp) by the
message

   (5) kernel: elogind-daemon[1877]: System is rebooting.

But the last update of "sys-auth/elogind" to version 252.9-r2 was end of
September and thus _before_ my last successful reboot  via Xfce's action
buttons and without the symbolic links.  So "elogind" seems out.

As is kernel 6.6.58-r1, because booting an older kernel (6.6.52) without
the symbolic links didn't work either.

So currently I'm  a bit out of ideas,  apart from leaving these symbolic
links in "usr/bin/" :-(

Sincerely,
  Rainer

I have no split-usr system here to compare notes, but did you try rebuilding 
the sys-auth/elogind package just in case?

Yes, I did.  With and without USE flag "cgroup-hybrid" which was enabled
by default up to version 246.10-r4 including  but is disabled by default
in version 252.9-r2.  Didn't change anything :-(

My old rig is split-usr.  If you need info from it, I can boot it up and
get it.  Just let me know what commands you want ran.  I update it once
a month so it is fairly up to date.

Greetings,

Well, it turned out my tests have been a bit too quick and dirty.  After
re-emerging package "sys-auth/elogind"  the old "elogind-daemon" service
programme is still executing  and thus clicking on  Xfce's "Restart" ac-
tion button only tests the old binary in its new environment which -- of
course -- isn't guaranteed to work :-(

So between re-emerging  and trying to reboot via Xfce's "Restart" action
button I need to reboot using "/sbin/reboot" to run the "elogind-daemon"
service programme I want to test.

Using this slightly more sophisticated test procedure  I found that both
stable "sys-auth/elogind" ebuilds work while BOTH BINARY PACKAGES DON'T.

As already described in a previous mail, after pressing Xfce's "Restart"
action button  the system stalls or loops indefinitely,  and syslog con-
tains

   2024-11-18T17:55:02+01:00 (5) kernel: elogind-daemon[1835]: System is rebooting.
   2024-11-18T17:55:02+01:00 (3) reboo[5780]: Failed to execute /usr/bin/reboot: No such file or directory

which somehow suggests that "elogind" expects "systemd" to be installed,
while I'm using "openrc".

Quoting a slightly outdated Gentoo webpage [1]:

   The available useflag settings and versions correspond to the
   stable packages of the amd64/17.1/nomultilib (i.e., openrc),
   amd64/17.1/desktop/plasma/systemd, and amd64/17.1/desktop/gnome/systemd
   profiles.

Apart from the outdated "17.1", I'm on neither of these profiles:

   $ eselect profile show
   Current /etc/portage/make.profile symlink:
     default/linux/amd64/23.0/split-usr/desktop
   $

Is THIS the problem?   But if -- as the above quote is suggesting -- the
binaries are coded to work with BOTH,  "openrc" AND "systemd",  then why
don't they work on my laptop?

Baffled,
 Rainer
