RR/6/4 is 100% pure gentoo

We just made it so that mostly everything works right out of the box. We are moving towards a new name of Sabayon Linux, and everything we do in SL will again be 100% gentoo compatible. This saves you a lot of time with configuring a kinda hard distro to learn at first...but once you learn it, the power of gentoo is very evident... hope that answers your question. rr4 is 32 bit and r64 is 64 bit, so why don't you d/l and check it out
