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

+Be carefull to keep the ''control-alt-delete.conf'' service as it is used to shutdown the vserver with ''vserver <vservername> stop'':
+<code>
+: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)

+===== Add vserver init task =====
+Create the file ''/etc/init/vserver.conf'':
+<code>
+description     "Vserver init"
+start on startup
+console output
+task
+pre-start script
+       touch /var/run/utmp

+===== Tweak sysinit configuration =====
+In ''/etc/init/rc-sysinit.conf'' replace the following line:
+<code>
+start on filesystem and net-device-up IFACE=lo
+</code>
+by:
+<code>
+start on filesystem

+===== Tweak ssh configuration =====
+In ''/etc/init/ssh.conf'' comment the following line:
+<code>
+# replaces SSHD_OOM_ADJUST in /etc/default/ssh
+#oom never

+===== Create the console device =====
+Missing of ''/dev/console'' makes all scripts with ''console output'' fail. First think would be to create the ''console'' device inside the guest but this should be avoided:
+<code>
+: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
+</code>
+I use ''tty'' so the console outpouts on the current tty:
+<code>
+# mknod --mode=600 /etc/vservers/<vservername>/vdir/dev/console c 5 0
+</code>
+If you want to troubleshot from outside the vserver you can use for example ''tty8'' as the console device for vservers:
+<code>
+# mknod --mode=600 /etc/vservers/<vservername>/vdir/dev/console c 4 8
+</code>
