Examples: special network share or flash drive,so I can easily identify them.
Ubuntu 11.04 Gnome Classic.
UPDATE: By "special network share" i mean network shares which are "permanently" mounted using the fstab
e.g. in my case samba shares on my home server. I have one for music and one for other stuff.
It would be totally fine for me if the icon is on the share or drive and some (hidden) auto-loaded configuration file knows where it is.
