Which init system for Debian?

*Sigh* There are two way to "socket-activate" a process.

All start by actually opening a socket and listen()ing to it. When a connection request arrives,

(a) accept the connection, start a new server, hand the new connection to it on stdin/out. This is, in general, not a good idea because you pay the startup cost for every request.

(b) DO NOT accept the connection; instead, start a new server, hand the listening socket to the server (typically on stdin). Ignore the socket until the server dies. (x)inetd, systemd, upstart, … all can do this.

The condition "the server dies" obviously does not work if the daemon forks-and-exits for whatever reason. xinetd also does not work for you if a server wants to listen to multiple sockets, or (these days) should start when an udev request arrives for it … or maybe you want to manually start the thing because you know you'll need it in a few minutes …

… and shutting it down cleanly has its own grab bag of problems, which (x)inetd does not address AT ALL.

I mean, come on. You can find some piece of code which does a half-assed job of (almost) anything systemd can do . What nobody in this whole discussion has ever mentioned is a program which today improves on anything that systemd can do.
