Since I install schroot environment I have trouble during
shutdown/reboot of my computer. Detailed inspection shows, that cause is
schroot-session-management. Session is leaved in
/var/lib/schroot/session and mountpoints in /var/lib/schroot/mount is
not automatically unmounted, what produce filesystem damage.

It is strongly direct to replace script /usr/local/bin/do_schroot from
my how-to with this:

#!/bin/bash
PROG="`basename $0`"
ACTSESSION=`exec schroot -c etch -b`
schroot -p -r -c $ACTSESSION -- "$PROG" "$@"
sleep 30s
schroot -e -c $ACTSESSION

Within it appears directly begin and end of session, what release trouble.
