Hi,

You might be surprised what init is executing during boot :)
http://c-skills.blogspot.com/2007/11/boot-graphs.html

Same can be applied to any startup sequences like startx, startkde
etc.
The Linux 2.6 kernel comes with a nice interface which makes
this possible. Also the new inotify(2) API is worth studying,
especially if you are stuck in a race-exploit :-))
Years ago I wrote a generic /proc based exec-scanner
which also worked on *BSD, but this one is much more reliable b/c
its un-racy.

enjoy,
Sebastian
