CAUTION: Do *NOT* rm -rf the chroot directory; if there are stale bind
mounts you may end up deleting your source tree too.  To unmount and
delete the chroot cleanly, use:
$ ./new_make_env.sh --delete --chroot=../../gchroot
ferar@barbarian:~/chromiumos/src/scripts$ cd ~/chromiumos/src/scripts
ferar@barbarian:~/chromiumos/src/scripts$ ./enter_chroot.sh
