The root cause of the problem is this:

rhertzog at rivendell:~$ mount | grep sarge
/etc on /home/rhertzog/local/chroot/sarge/etc/.host type none (rw,bind)
/home on /home/rhertzog/local/chroot/sarge/home type none (rw,bind)
/tmp on /home/rhertzog/local/chroot/sarge/tmp type none (rw,bind)
/dev on /home/rhertzog/local/chroot/sarge/dev type none (rw,bind)
proc on /home/rhertzog/local/chroot/sarge/proc type proc (rw)

I have already mounted everything needed in the root chroot. Up to now,
we could happily mount /proc several times at the same place, now it seems
to fail (but bind mount can be mounted several times, at least mount
doesn't complain).

Maybe can you check if /proc is already mounted before trying the mount?

Cheers,
