How can we best support different init schemes?

There are several different init systems present in Debian - However, we are only supporting currently one of them, good ol' sysv-rc - We have close to a thousand packages providing init scripts suitable for it, and close to none for all of the other systems. In current systems, full of hot-pluggable devices, changing network configurations and so on, however, I think this situation is quite prone to change - sysv-rc and its runlevels are better suited for stable server-like systems, and is hard to adapt for future needs. We will talk about the potential difficulties Debian will face in order to better support more init schemes, and discuss some ideas to solve them.
