Additional context

The last change in that template was done for #120163. Then we ran into problems that were likely caused by the salt mine not being populated. However, this is now a different error and if the line the logs point to is correct than it now even fails before the modifications from #120163. So I've been creating this new ticket (instead of reopening #120163).

The problem persists after retrying the pipeline and also shows when invoking state.apply manually on OSD (and I ran into "The function "state.highstate" is running as PID …" again). Maybe https://gitlab.suse.de/openqa/salt-pillars-openqa/-/commit/9f6245d521c5ba4145a485f802b64f09f9998dd2 or some other pillar-related MR caused the problem. I'll try to revert it "locally" on OSD and see if it changes anything.

It is that MR, indeed:

martchus@openqa:/srv/pillar> sudo git revert 9f6245d521c5ba4145a485f802b64f09f9998dd2
[revert-9f6245d521c5ba4145a485f802b64f09f9998dd2 f89df66] Revert "Add IPMI contact details for w16/17/18"
 1 file changed, 12 deletions(-)
martchus@openqa:/srv/pillar> sudo salt '*' saltutil.refresh_pillar
…
martchus@openqa:/srv/pillar> sudo salt -l error --state-output=changes \* state.apply
…
[everything looks good, including workers]

I'll create a MR to fix the syntax.

The SR has been merged. I've already checked it in production before so I'm confident it works. Also haven't seen any pipeline failures anymore.
