Ahh so that's where the timeout problems occur. OK, that makes sense indeed.
Just need to work out when /var/run symlink when missing.
Sadly, I need to get systems where this keeps reoccuring, sadly by
completing the upgrade fully it now means we can't debug the causes.
Hopefully someone will be able to reproduce it on a snapshotted VM so we
can reply various scenarios :)

Yeah completely understandable. I'm sure we'll find a way to reproduce
it in laboratory settings :)

Yeah, the mandriva-clean-var-run-lock.service is no longer shipped in
cauldron/mga3's initscripts package (with the move to /run it's no
longer needed).
I'm still confused as to what's causing the problem tho'.
I don't suppose you happen to have a left over broken symlink to
mandriva-clean-var-run-lock.service somewhere in your
/etc/systemd/system/ tree? If so what's the exact path? (you can safely
remove it now if it exists).
