The idea is then to make some kind of meta-script which would be then converted to all the rest of the systems, such as the way menu entries are handled? Will it be possible to design one for all?
I don't think this is possible. upstart, initng and sysvinit et al have completely different paradigms (event based vs. dependency based vs chronological order). I also don't think it will be possible to translate existing initscript (shell scripts) in an automated fashion into upstart jobs or initng ifiles. Shell syntax is simply to complex What we should push for as first step though, is making sysvinit non-essential (I already wrote about this topic wrt upstart on the d-d ml last year) and introducing an new package, let's call it "initcore" for now, which provides the core infrastructure, like update-rc.d/invoke-rc.d, and make that package essential. This package could then have a dependency on "sysvinit | initsystem". Packages like upstart could then have a Provides initsystem. If one of the replacement initsystem proves to be the most promising one (which imo is upstart atm) we can switch the default later on. As a next step we should scan existing dpkg maintainer scripts/init scripts and logrotate files and check if they use invoke-rc.d properly or call /etc/init.d/$scripts directly and file bugs against these packages. We will need this so replacement init systems can divert invoke-rc.d/update-rc.d. As maintainer of upstart, I already thought about this topic alot. As soon as I have some spare time, I'll write something more detailed.
