What are your 1/2 dozen things?

I’ve swapped distro (openSuSE to ARCH) and except for a few DISTRO items I had no trouble. IE getting mythweb working was such a task that I’d *never* forget what I did, but before I documented what-I’d-done I forgot :-(
(and in case anybody references this: using the distro packages I was unable to get everything working - and I really tried)
