You can force the mountpoint to uid and gid (non-Rock Ridge, RR will keep the normal settings of the mountpoint, so change that directly with ch[mod|own|grp]), but it seems setting the permissions of the mount point (and underlying directories) can't be done (non-RR sets 444 for files and 555 for dirs/mountpoint). Setting the permissions of the actual _files_ on the CD (non-RR) can be done with the mode=xxx BEWARE! As far as I can see the mode is interpreted as decimal numbers and then converted to octal!!!! mode=506 gave rwxrwx-w-, 505 gave rwxrwx--x !!! It would seem that there's no way to prevent users from at least listing the files on the CD (non-RR), although they might be prevented from reading the contents of the files. /Michael -- | Linux: Turn on...Tune in...Fork out... | | Michael Tempsch, member of Ballistic Wizards, TIP#088, TDGP#20 | | [EMAIL PROTECTED] | [EMAIL PROTECTED] | [EMAIL PROTECTED] | | Cell.Phone:+46 705487554 URL:http://www.dtek.chalmers.se/~d1temp | -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] .
