The branch stable/14 has been updated by des: URL: https://cgit.FreeBSD.org/src/commit/?id=b41551753a2baff6646e2958acb4a7fcd205b69c commit b41551753a2baff6646e2958acb4a7fcd205b69c Author: Dag-Erling Smørgrav <des@FreeBSD.org> AuthorDate: 2025-10-17 11:55:12 +0000 Commit: Dag-Erling Smørgrav <des@FreeBSD.org> CommitDate: 2025-11-19 11:19:07 +0000 quot: Add tests To facilitate the task, we change the comparison function so that users with equal filesystem usage are sorted by UID, and add an undocumented option that prevents quot from replacing numerical UIDs with names. We also switch from getfsfile(3) to getmntpoint(3) so the first line is identical regardless of whether we pass quot a mountpoint or a device.
