   Is christos commit sufficient to fix this?

It would seem appropriate to me for /proc/mounts to match the
behaviour of getvfsstat, which christos's change doesn't quite
implement -- getvfsstat doesn't show the full path of any mount point
even to the superuser, and it fakes an entry for a root file system if
the chroot is not itself the mount point of any real file system.

That's what I tried to do in the patch I suggested, although I botched
something about the root file system fabrication.
