[libvirt-users] upstart script for virtlockd

[NEVEU Stephane]

Hi Eric,

Here is my try to write a quick upstart script for virtlockd. 
It should be named /etc/init/virtlockd.conf, then : ln -s /lib/init/upstart-job /etc/init.d/virtlockd
It seems to work for me :

# virtlockd - Locking daemon for libvirt
description     "virtlockd"

start on filesystem and runlevel [2345]
stop on starting rc RUNLEVEL=[016]

pre-start script
    test -x /usr/sbin/virtlockd || { stop; exit 0; }
    test -c /dev/null || { stop; exit 0; }
end script

script
    start-stop-daemon --start --make-pidfile --pidfile /var/run/virtlockd.pid --exec /usr/sbin/virtlockd >> /var/log/libvirt/virtlockd.log 2>&1
end script

It looks like virtlockd was added after Fedora had already moved over to systemd, so no one has bothered to write an upstart init script for it yet.  Patches welcome.

Yes, I think that's a reasonable workaround in the meantime.
