I use the git repo as a "scratch pad" of sorts and toss anything in there that's relevant to my issues but not yet "fully baked" so it has a bunch of crappy ad-hoc scripts, config files, patches, etc. They'll all related to the issues in my private repo and only live in there long enough to get cleaned up. Anything long-term moves into a configuration management repo, my personal dotfiles repo, a repo of it's own, or upstream.
