Thought it was time to do a reinstall of my server/development pc (called Ayanami)...
Since it was more of a hassle to do an update (especially with the gcc update from 3.4 to 4.1), I decided to do a reinstall.
I wiped out my very old 2005.0 install cd, mkfs'ed the / and /boot and downloaded the 2006.1 stage3 and latest portage. Installation went smoothly, and it's currently merging the necessary stuff: Apache2, PHP (apparently Gentoo has moved to PHP5 as the default), MySQL5, etc.
Later on, I'll probably install a desktop environment as well, but haven't really decided whether I stick with KDE, or move to another one. The eventual idea is to get a TV-tuner card (probably some bttv-chipset) and use it as a sort of a multimedia-system, aside of the development server task it's doing right now.
