Are you aware of the existence of /etc/debian_chroot?  This is
already used by the bash shell for its prompt:

$ schroot -c unstable
I: [sid-amd64-sbuild-c8773e4d-a52b-4378-9975-baaeb3c2bd48 chroot] Running login shell: ‘/bin/sh’
(sid-amd64-sbuild)rleigh at ravenclaw:/tmp$ cat /etc/debian_chroot
sid-amd64-sbuild

(unstable is an alias for the sid-amd64-sbuild chroot).


I can add a SCHROOT_SESSION_ID environment variable very easily.
Adding the original chroot name is somewhat harder (it's replaced
by the session ID, and so is not longer known at the time we set
up the environment).  I would need to store the original chroot
name somewhere for that.

Roger
