No, this time it is you who are confused. UFS_DIRHASH does not affect the layout on disk at all as far as I can tell. You are probably confusing it with the dirpref changes that were made back in 2001 at approximately the same time as UFS_DIRHASH was added. -- <Insert your favourite quote here.> Erik Trulsson [EMAIL PROTECTED] _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
