It seems like it's:

TTYGRP=5
TTYMODE=620
[ -f /etc/default/devpts ] && . /etc/default/devpts
domount devpts "" /dev/pts devpts -onoexec,nosuid,gid=$TTYGRP,mode=$TTYMODE

so I can do similar in pbuilder.


I really don't like the look of this because it's some random config
which is shared between inside the chroot and outside of chroot, but
it needs fixing.
