two sshd daemons and pids

[CAMTP guest <camtp.guest@uni-mb.si>]

I'm trying to setup a second sshd daemon (with different configuration
and port listening), but have a problem with the PID file. Apparently
the start-stop-daemon ignores the --pidfile $PID directive.
When I start the second sshd daemon (the /etc/init.d script attached),
the original /var/run/sshd.pid is overwritten instead of the new
/var/run/sshd-1.pid created. As a result there are of course problems
when stopping any of the two daemons. Otherwise, it works fine.
