My point is those byte ranges might differe from one version of that file to another. Bleaching byte ranges could only affect the current FS, not any snapshots/clones. (Of course, if we decide that snapshots are so read-only that we can't provide a bleach facility that bleaches across snapshots, then that's fine.) _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
