Breaking out of a chroot on the Hurd is trivial: just use a passive
translator. A passive translator will inherit the namespace of the
file system which started it, not the process which set it. Thus, a
chroot'ed user need only run:
settrans -c root /hurd/firmlink /
Neighbor Hurds won't suffer from this problem.
I don't have any ideas offhand of how this could be fixed.
Thanks,
Neal
