And finally, the moment you've all been waiting for... *drumroll*... Slefika 11.0!
Instructions and files are accesible on:
http://coderock.org/slefika/It seems to work quite nice. Even X with xfce and seamonkey.
note1: Yes, I know Slackware 12.0 is out for some time now, and I do plan a new release.
note2: Just noticed this: if you're doing serial console install you won't be able to log in after boot because ttyPSC0 is not in /etc/securetty (so boot with init=/bin/sh; mount -o remount,rw /; and fix it).
