Error when try to shutdown system -/run/initctl

[2bbionic]

Hello,

I accidentally switched over to systemd and tried to roll back to the openrc procedure a couple of days ago. Unfortunately something went wrong and I don't know what so maybe you can help here.
The system is a XEN guest and I uninstalled systemd already and installed openrc again (with udev). I also did a emerge -avND @world which didn't complain (after adding systemd to my USE)
emerge --info shows:

Hi

What is the error output?

Please try

Code: Select all

emerge -1av sys-apps/sysvinit

Try this also

Code: Select all

openrc-shutdown --poweroff ###Or 
openrc-shutdown --reboot

What is the output of

Code: Select all

ls -l $(which poweroff)

?

[2bbionic]

Code: Select all

 openrc-shutdown  --reboot now

was OK, after re-emerging sys-apps/sysvinit

But when I try "reboot" I got this:

Code: Select all

Maybe reemerge openrc?

How do you "accidentally" switch to systemd?

Post the output of ps -p 1 -o args.

I wonder which process creates this file..

sysvinit's init program.

OK, openrc-init is process 1, i.e. currently this is a 'pure' OpenRC setup. Did you really want this setup, or did you actually want the standard sysvinit + OpenRC setup? Also, post the output of emerge -pv openrc.

[2bbionic]

No, standard would be nice

The output if emerge -pv openrc:

Code: Select all

emerge -pv openrc

These are the packages that would be merged, in order:

Then this is correct. The sysv-utils USE flag unset.

As a final check, see if the output of file /sbin/init says it is an ELF executable instead of a symbolic link. If it is, you can reboot to sysvinit with openrc-shutdown -r now and after that, the regular reboot program should work as expected. Unless you have an init= parameter in your kernel command line, the output of ps -p 1 -o args should change to:

Code: Select all

COMMAND

, it's not linked

and nothing happens anymore (no reboot)

If you have a /run/initctl file, remove it and try again. It will confuse openrc-shutdown. It will reappear once you reboot successfully to sysvinit.

Im my xen config file, I have this:

Code: Select all

# Sets runlevel 3.
extra = "init=/sbin/openrc-init 3 xencons=tty console=tty"

If you want a standard sysvinit + OpenRC setup, this is wrong. Remove the init=/sbin/openrc-init and 3 before rebooting (I'm assuming Xen passes these as kernel parameters).

[2bbionic]

I hadn't aninitctl in /run.
I removed the init=3 from my xen config ; now it does not complain anymore but

INIT: Entering runlevel: 3

So finally reboot/poweroff works again and the pipe for initctl also is created in /run

Thanks for your support!

Kind regards,

Andreas
