Possible maybe, however, any value returned by restic wouldn’t be comparable to a traditional filesystem and be rather slow to compute (imagine running the stats command).
Changing the fs name would actually be rather simple: restic/cmd/restic/cmd_mount.go at 2280fbfd2e8e3b6eeba8ebaa95d06b9e4519ced9 · restic/restic · GitHub . However, I don’t completely understand what you mean with “repo_name”? We could show the repository ID that shown when opening a repository repository a14e5863 opened (version 2, compression level auto). I don’t think that we should show whatever path was passed to the --repository option of restic.
