Tzafrir, I kind of suspected that the init scripts weren't a great example because of systemd. It's already in Fedora 15, but I have to plead ignorance to its implementation. I thought it still used text-based service files, but I'm only familiar with it from reading the large number of posts it has generated on the Fedora users list. That's actually started to settle down and Gnome 3 has emerged as the new whipping boy. Since systemd has been proposed as a dependency of Gnome 3, this has the potential to create singularity that will destroy the universe. ; ) Personally, I'm not really excited about any of the optimizations that you listed. I can manage which services are started and the Linux boot sequence is pretty fast already. It's far quicker than the serial initialization of hardware that our servers go through at each boot. So for my use case, it can still be cited as an example of optimizing the wrong thing. In the long run, it's likely to save me very little time compared to the amount of time spent learning the new system. I'm sure it has its benefits and I'll come to appreciate them over time, but SysV init ain't broke (for me) so I'm not looking forward to fixing it.
