Slightly OT here:
"thinking ahead" lately, I was curious how I might bring my Squeeze based SheevaPlug to Wheezy when the time will come.
As I'm a U*X n00b andf as I didn't find any upgrade guidelines for squeeze -> wheezy, yet, I think I adopted this one
http://www.go2linux.org/how-to-upgrade-from-debian-lenny-to-squeeze, which explains the steps for Lenny to Squeeze. IMO the upgrade worked, though I did it on a spare plug with a fresh squeeze install only at that point in time.
When I have some spare time maybe I'll be "brave enough" to try it on my production device (after cloning the SDHC card, though

). Or is there anything else I should consider, first?
