If it's so ugly, why do Solaris and Irix not have a problem in making a device graph that looks somewhat like that as well? The idea is *not* so crazy as to discard out-of-hand. Perhaps what you need is: /dev/hda/disk whole-disk access /dev/hda/0 partition 0 /dev/hda/1 partition 1 ... etc > It reminds me of AIX from the days when it ran on PCs. > They had this neat trick of "hidden directories" (for a different > purpose).

You think that was ugly, you should have seen it around the F17 level when there were still some bugs in there (you haven't lived till you see the ooglyness of an 'rsh' between TCF cluster members of different flavors - it propagated the environment variable that controlled that stuff.. :) Incidentally, I'm told that HP/UX has a similar concept, at least in some releases... --==_Exmh_1099027620P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (GNU/Linux) Comment: Exmh version 2.5 07/13/2001 iD8DBQE//G40cC3lWbTT17ARAqcvAJ9plo3py/o6fNMrdQ8qsNGtxOSSBACffe3i 2PkjanrvzGqr0bT4iko0N5Q= =ZETh -----END PGP SIGNATURE----- --==_Exmh_1099027620P--
