 ====== Fix for running Ubuntu Lucid in vserver ======

+:57 <@Bertl> well, regarding console: you probably don't want 'the console' created inside a guest, because that means that
+               upstart (from the guest) will write on your host console (and can read stuff from there too)
+:58 <@Bertl> what you want is to put a tty or pts there instead of the console, or if you like to see the output on the
+               current tty just tty
+:59 <@Bertl> regarding the stop: your guest seems to ignore the 'normal' init signalling which is done when a guest is shut
+               down
+:59 <@Bertl> thus, after a given (configureable) timeout, the guest is killed instead
+:00 <@Bertl> util-vserver does not execute stuff inside the guest, it simply sends a signal to init (inside the guest)
+:01 <@Bertl> (the singnal is SIGINT, and this equals to the CTRL-ALT-DEL action)
