Title:
per-instance is not run after reboot during boot
Status in cloud-init:
Expired
Bug description:
Bumped into a problem with missing user after node reboot during per-
instance module execution. What happens is that the file lock is
acquired, but module does not finish before rebooting[1]. After reboot
we can see that cloud-init thinks module ran successfully although it
was interrupted before succeeding to add user[2]. And later we can see
other modules failing due to missing user[3].
I suppose there is attempts to run same module multiple times at the
same time so we need to have the lock file written before module
execution? Obviously would be easiest if sem.lock() could just be
moved to after execution. If this is not possible, I guess the locking
could be improved in a way that has_run() would distinguish module
running/finished from module failed mid-run on first boot.
