Think you've mastered Linux? Prove it, with Suicide Linux
Why would you ever want to play Suicide Linux? Well, it's certainly not practical, but it makes more sense as a game than as an actual operating system. See how many days you can make it without erasing all your files! Hell, I probably wouldn't even be able to survive Suicide Mac OS X for more than a week (sometimes I flub my Quicksilver commands when I'm tired, okay?!), so Suicide Linux sounds to me like a test invented by an overdramatic movie villain.
Unfortunately (or maybe fortunately), I couldn't find an actual download of a Suicide Linux distro, but it seems like it wouldn't be that difficult to create ... especially for someone who could use it.
