Hi list again, another suggestion.
I use the deamons pidfile feature to write pidfiles so I can controll
the virtual machines with /etc/init.d/bla scripts, to e.g. auto spawn
the guests when the server starts, auto/start/stop with runlevels and
so on.. However I got following issue, the daemon wont start if there
is a pidfile already (yes no problem for user to delete, but for auto
spawning after unattended boot) . Since e.g. following situation:
BANG! Powerout! .... System goes up when power is available again. The
init scripts want to start the qemu/kvm deamons, but they refuse
because these see their pidfiles already from pre-powerout..
-pidfile behaves properly in CVS. You may be able to find the patch on
the ML that fixed it.

I have seen other daemons somehow locking their pidfiles while
running, and when killed -9ed, or poweroutes and they start again,
they see their pid-file is unlocked, thus stale, and just overwrite
it... only notifing you with a message they did so.
Kind Regards,
Axel
