gnome 2.8 Changes for FAQ: 19. How do I mount my removable media in Nautilus?

[Franz Klammer]

gnome 2.8 hase some changes in handling of usermounting
removerable volumes and i think that should be added to the FAQ.

1. don't use mounting points that are symlinks
   if /home is a symlink to /usr/home it is important that
   in /etc/fstab is the real path entered e.g.:
   /dev/acd0 /usr/home/username/mnt/cdrom ...

   if someone mounting to /home/username/cdrom the directory/mountpoint
   will be changed to root:wheel _and_ the original (unmounted)
   icon is still to see in Place Computer (of course also the cd-rom icon)
   and when klicking on it nautlius claims that the device is bussy.

2. there are naming conventions of the mounting points:
   (relative to e.g.: /usr/home/username/mnt/)
    CD-ROMS       => cdrom
    CD-RW         => cdrw
    Memory Sticks => memstick
    and so on ...

    without that nautilus didn't work correctly.
    i had hours with trying and trubles until figured this out... :-(

    attached the gnomevfs-function where i found all the names.

3. (maybe) OT question: when i insert my memory stick the access right set
   for the device created by usbd (/dev/da0s1) don't allow access from a
   normal user. currently i helped my with a dirty trick:

   adding to /etc/devfs.conf:
      perm da0s1 0666

   and to /etc/usbd.conf:
      device "MEGA"
           devname "umass0"
           attach "/bin/sleep 5; /etc/rc.d/devfs restart"

   if there is a (which i'm sure there is) a good solution that
   should also be added to the FAQ.

   here to see how it looks like two screenshots of "Computer":
