Sidenote:
That's really a feature and you can also use it in a sane way by having
a "nodev" file instead of a "dev" file in the directory for that ip
address. That way, the ip address is assumed to be already setup and
will neither be created when the vserver is started, nor be destroyed
when the vserver is stopped.
