i have NOT installed linux on my xbox, but ive installed linux many times on a PC
and ive install gentoo many times on PC's
So for a small install of gentoox, asumming its somewhat like installing on a PC, just install the base install, followed by a system logger, if you choose, then install samba
ul have a small install of gentoo with a samba server, having only samba, base install.. (which is just a few services and basic executables)
Perhaps someone who has installed gentoox can verify/drop what im saying... <
