But don't CD-ROM and floppy devices also need the same sort of pmount support you're proposing here? After all, you can hot-swap the media in them, so it seems reasonable to me that they can be pmounted? What's the rationale for _not_ including these in the pmount infrastructure you're proposing? Hmm. Now that I think about it, surely the plugdev group would have to be given using pam_console so that remote users in the plugdev group can't remotely stomp on the USB memory stick the local user just put in, before they could mount it? In _that_ case, cdrom and floppy strike me as _very_ appropriate for the same treatment, and the local administrator could add appropriate people directly to those groups for things like a headless server where someone whacks in a USB stick, and then wanders back to their laptop to access it. This would close (to my mind) a security hole in systems where both local and remote users have access. -- ----------------------------------------------------------- Paul "TBBle" Hampson, MCSE 7th year CompSci/Asian Studies student, ANU The Boss, Bubblesworth Pty Ltd (ABN: 51 095 284 361) Paul.Hampson@Anu.edu.au "No survivors?
