If you are using it do you want to maintain it?

[felixonmars]

I'm packaging it for Arch as it's still used by test suites of darcs and persistent-sqlite. I can help maintain it as long as it's still used.

[andreasabel]

I added you on Hackage (felixonmars), also for the system-filepath sibling package (which is used a bit more).
