updating unslung-nslu2 to debian

had some trouble with this so thought I'd post

1. the unslung web/cgi updater doesn't work in unslung, so you have to use "upslug2"
2. the debian autoinstaller didn't work for me because I couldn't get a mirror to give me the goods so I ended up formatting my flash drive appropriately, installing the debian image to it and upslug2-ing a special? image to that, see here: http://www.cyrius.com/debian/nslu2/unpack.html
