+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>
-# mknod --mode=600 /etc/vservers/<vservername>/vdir/dev/console c 5 1

+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
