After stracing, it is indeed looking for:

  trash directory.t7900-maintenance/systemd/user/git-maintenance@hourly.service

but that file doesn't exist. We installed git-maintenance@hourly.timer,
and git-maintenance@.service. Is the latter supposed to be a wildcard of
some kind? Maybe the rules changed. I don't really know anything about
systemd.
