No, the reservation in UFS/FFS is to keep the performance up. It will be harder and harder to find free space as the disk fills. Is is even more important for ZFS to be able to find free space as all writes need free space. The root-thing is just a side effect. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
