I haven't looked at the implementation, but a useful feature that's
usually missing is these multi-instance implementations and that is
available in the multi-rc.d scripts scenario (take tomcat7 rc script
as an example) is the ability to start/stop a single instance. Not
always the instances are related each other, sometime they serve
completely different purposes/applications and would be very useful to
allow starting/stopping them independently. If we can get the best
from the two implementations it'll be a win-win solution.

I like the idea of defaults inside the scripts, but I like also a file
that lists all available knobs with default values. If it can be
automatically generated from the scripts for human reading purpose
only, I'll appreciate it.
