Well, that's not what it's doing. Why aren't you just running killall5 at
the end of rcK? (Also note that util-vserver will kill all processes in a
guest if they're still around after the stop process is completed.)

Yes. See e.g. the gentoo distribution for an example of how to change the
configuration from the initpost script.
