This removes all the subdirectories in `config` on start. From one version of GitLab to the next, the files in the `config` directory changes. Since we're only overwriting the existing files with ones from the repo, cruft sometimes gets left behind, occationally causing issues. Ideally, all configuration put in the `config` directory is declared by NixOS options and we could just remove the whole directory on start, but I'm not sure if that's the case. It would also require a little bit of additional rework and testing. The subdirectories, however, should seldom contain user configuration and the ones that frequently does, `initializers`, is already removed on start.
