Well, color me confused. You appear to be saying that the permission on a file differ depending on which link you are accessing it by. Furthermore, your stance seems to imply that linking to a file grants either write permission or ownership on the new link. So, under this permission model, I could link to /etc/passwd in my home directory, edit the link to change my UID to zero, then relogin to the system as an administrator. Not that I would need to, of course, because any user who owns/could write to a directory would be able to alter any file on the entire system. I know they're called "permission" models, but that seems *extremely* permissive... --=20 -Julian Blake Kongslie --Signature_Wed__5_Oct_2005_13_41_09_-0700_clQzPPH.H409/=pW Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) Comment: Don't have my public key?
