Quota initialization is correctly done against the right mount point: vfs_quota: enabling accounting for /boot (ufs) vfs_quota: enabling accounting for /tmp (tmpfs) vfs_quota: enabling accounting for /home (nullfs, /pfs/@@-1:00001) but the nullfs mount code uses a hack to replace it's mount point information with the one of the underlying non-nullfs filesystem In the above example, /pfs/@@-1:00001 is a symlink on the root volome. So, once the real write operations are done, they are all counted against / > I may be totally misunderstanding this. I'm afraid not :-( So far, I've not found a way to obtain the _real_ mount point information when a write operation is done on a nullfs volume. -- Francois Tigeot
