Frankly, time issues aside, I wish Debian & co. (I use Ubuntu on the Desktop, with Debian running some servers) would go low impact. Common lisp controller is an annoyance and it is pretty much impossible to package most libraries in the common lisp ecosystem. It is too unstable, too readily changing, so if you are making serious use of many libraries you need to use SVN/Mercurial/Darcs/Whatever to get the source and keep it up to date.
