We currently don't make any provision for doing this--you would
need to do something as in the example you gave.  However, I would
certainly not oppose having some generic method for starting and
stopping services inside schroot chroots which would allow one to
specify a chroot to begin a session with and then actions to
start and stop services.  If it was limited to init scripts only
then this would be very simple to do; we would just need to
record the session ID plus the services started in /var/run in
order to reverse the procedure.  If limited to services, we could
create a directory e.g. /etc/schroot/autorun and have files in
there defining which services to run in which chroot, e.g.

[unstable]
  postfix
  postgresql-9.0

[unstable]
  postgresql-8.3

[stable]
  apache

as a simple example.  Any thought on what information is needed
would be very useful.
