I was under the impression that /var/run was always cleaned out on
reboot, so this shouldn't be a problem. Is my impression wrong?
And I think the point of the lock file was the sm-notify would only
run once per reboot. You really wont it once per
lockd-forgets-all-locks so a kill -9 on lockd should be combined with
removing the lock file.
But I think that removing the lock file when sm-notify completes is
Note the comment in sm-notify.c:
* Record pid in /var/run/sm-notify.pid
* This file should remain until a reboot, even if the

* If file already exists, fail.
