Hi viverna,
Hi Steve Litt, thanks for the reply.
I'm not quite sure what you're trying to accomplish, but if
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?
If service_required should still be running when my_service starts up,
then service_required should have its own /etc/sv/service_required and
the symlink in /var/service, and a test should be devised to determine
whether service_required is functional. Let's say that test is
contained in a shellscript called service_required_is_functional, that
returns 0 when the service proves it's functioning, and some other
number otherwise (I use 1). Then the run script for my_service looks
like this:
#!/bin/sh
if service_required_is_functional; then
exec my_service
fi
sleep 1
Very interesting. Simple and useful. I will try your solution as soon
as I have time available.
