Based on feedback I received on my initial diff, I took another crack at user mounting. To address Robert's concerns, I drop the setuid permissions until needed. Therefore, all permission checks are now done in the kernel. The same is true for umount(8).
silby asked for wildcard support. To handle that, I added glob support to both the fs_file and fs_spec fstab components (via fnmatch(3)), and also added a special %u pattern that can be used to represent the current user (i.e. the user running mount(8)). This effectively allows the following in /etc/fstab: //[EMAIL PROTECTED]/homes /home/%u/smb_home smbfs rw,noauto,user 0 0 Then, a user could just run, for example: mount /home/marcus/smb_home And their SMB home directory would get mounted (~/.nsmbrc is also respected). Additionally, something like the following is also possible: /dev/acd0 /home/*/cdrom cd9660 ro,noauto,user 0 0 Same mount command works here: mount /home/marcus/cdrom Wildcards can also be mixed and matched. Finally, in testing this, I found a problem with smbfs, msdosfs, and ntfs relating to the statfs(2) f_flags field. smbfs always set this to 0, msdosfs didn't set this at all, and ntfs set this to all flags (not just those visible to statfs(2)). By fixing this, umount(8) works properly on relative paths to user mount points for those three file systems. http://www.marcuscom.com/downloads/usermount.diff Comments?
