After a week of about no sleep due to aweful heat, it was really rainy around here. So what are you doing with a rainy weekend? Right, improve openSUSE boot time :)
So with a little optimisation of things already in place (no magic, no new white paper material) I got the boot time for a default (KDE) installation of alpha5 (tried the one CD install, but had to install quite some things from factory to make it usable - e.g. Nimbus Sans looks horrible as default font) down from 32s to 26s. That's an improvement of roughly 20%!
These 26 seconds are basically split between these:
I think the biggest potential is actually in not having to wait for _all_ hardware to initialize before remounting /. When I accidently disabled these boot steps I booted in 18s - of course incomplete in general, but I had a working kde startup.
Now on to the magic.
