The state path now, since the transition from initialization in preStart to using systemd-tmpfiles, has the following restriction: no parent directory can be owned by any other user than root or the user specified in services.gitlab.user. This is a potentially breaking change and the cause of the error isn't immediately obvious, so document it both in the release notes and statePath description.
