I have it running but life will be a lot better when a version of Freelink is released for the LS2, which I know that someone is currently working on.
Wow, yeah. I just went down to best buy and picked up a linkstation with which to test, and went from hunk-of-metal-in-box to debian in about 20 minutes.
Gotta say that freelink is pretty nice. And easy, too.
