Generating a list of paths for restic to backup introduces some issues: - restic matches incremental backups by paths, changing paths cause new backups - logs and a lot of restic commands print all the paths, which makes it basically unusable Thus I've reverted to using static `paths` and excluding patterns via the `--exclude-file` argument. To reduce files to backup from `~/dev`, a preStart job was added to the systemd service: It clones the directory via `rsync` with `.gitignore` files being respected.
