 I still don't see how can this be possible :-( If /dev/shm is just a
symlink, there is no way that removing it from inside chroot can affect the
host file system. If it's a bind-mounted tmpfs file system, then destroying
its contents would indeed affect the host, but removing the mount point
itself still wouldn't do it.

 The only possibility I see is that schroot bind-mounts /dev itself. This
would explain the above, but does it really do this?
