???? Can you explain how you want to do this? It seems VERY unclean to me to
let svscan start the service and some init script stop the service after it
has been started. Is that what you want to do? What about checking the
runlevel in the supervise-run-script. If it's running in a runlevel where you
don't want it to be run, the service can shut down itself. In that way the
service (The daemon, proftpd or what ever) is never started. I think that's
working fine if you reboot the machine in a new runlevel. If you just switch
the machine to a new runlevel you have to send a term/kill signal to the
daemontools services to shutdown services that don't have to run in the new
runlevel. Or you can setup the init script of svscan (The ONLY needed init
script) to stop and start daemontools if switching vom runlevel 2 to 3 or
vice versa or what ever.

It doesn't hurt but it's also not looking good.
I don't agree, that these init-scripts are a good idea. You have to do things
to EMULATE svscans behaviour. You have to check the down flag, and if it's
set, you don't must "up" the service. Ok, that's pretty easy, but.... Well, I
have a bad feeling about this. The people who are switching to daemontools
are switching because they LIKE daemontools and if they LIKE daemontools they
don't want init scripts. If they don't like daemontools they are not
switching init.d-services like apache, proftpd and others to daemontools or
are not using daemontools at all.
