Oh yeah, that's one of the things that I'm tempted by. I just recognise that it'll be a bit of a time sink (not necessarily a bad thing), and I should probably try it on a spare device or drive first. I've just been too busy to be able to sink my teeth into something like that, but hopefully some day.

A good guide or wiki makes a huge difference — I opted for Arch as my first Linux run, for example, because I kept seeing the Arch wiki be a useful resource when learning about general Linux things. Similarly, I have had a nosy at the Gentoo handbook and that too looks like a thorough and accessible resource (though it's more Gentoo specific obviously).
