Following the ZDNet tale of this Debian server, there's not much news. as it just works!

I've also upgraded the Debian server approximately 15 times since May. Windows XP Pro has required approximately 35 updates, mostly security updates to various applications. Debbie installed the updates (including a couple of kernel updates) and the added applications and kept running. The XP Pro system required nearly 30 reboots with the 35 updates. I also got at least one update I didn't know about and one I would have liked to have heard about before it installed itself. So, hmm, who wins this criteria category?
BTW I do know that Debian Linux does reboot. I've deliberately rebooted a few times just to see if it does. It has only been shutdown deliberately, not by accident or by software failure.
