Bug#570382: after upgrade: "vlogin: openpty(): No such file or directory"

[Reinhard Brunzema <reinhard.brunzema@dimdi.de>]

As a workaround instead of stopping and restarting you might want to use vmount 
on the affected vservers:

# vmount foo -- -a

You will get some error messages for all already correctly mounted filesystems,
but you can enter your vserver again.

Running
###
for vserver in `vserver-stat  | tail -n +2 | awk '{print $8}'`; do
        vmount $vserver -- -a
done
###
will fix all your vservers - broken or not (and give some more error messages).
