Hi Steve Litt, thanks for the reply.

I'm playing with runit mainly because I like to study new things and
because I'd like to have various init system installed in my machine
and script/config file related for all daemon.

I think that users wants, like me, when they installed a daemon with
apt and friends script/config file created for all init system
installed.

Ideally it is possible to make this executing a script on event
"DPkg::Post-Invoke" and copy script/config file in proper directory.

I have already written a simple posix shell script that works in my
computer with epoch init system, but I need help because code is
written in my spare time (very little time) and need coder better than
me.

Finally for all init system supported there will be:
- a package for init system (for example runit)
- a complete collection of script/config file (for example
runit-init-collection-script) in a proper format
- above script copy/delete script/config file in the correct directory.

I don't know if this can be a feasible solution for to ensure init
freedom. What do you think?

Very interesting. Simple and useful. I will try your solution as soon
as I have time available.
