I look for the removable devices that are mounted in /media. Devices like FAT32 USB sticks or camera memory cards are mounted with their UUID because they have no label and I need to identify them.
For example: $ ll /media/ totale 28K drwx------. 16 c.cerbo c.cerbo 12K 1 gen 1970 KINGSTON/ drwx------. 9 c.cerbo c.cerbo 16K 1 gen 1970 1D59-EB48/ $ ll /dev/disk/by-uuid/ totale 0 lrwxrwxrwx. 1 root root 10 2 dic 20:27 c827ec3b-487d-4e63-9259-e24892a229a8 -> ../../sda3 lrwxrwxrwx. 1 root root 10 2 dic 20:27 8305427f-bace-42f5-aecd-540a85d1b164 -> ../../sda1 lrwxrwxrwx. 1 root root 10 2 dic 20:27 ea452bb1-d2f1-41e4-a129-4497e837439a -> ../../sda2 lrwxrwxrwx. 1 root root 10 2 dic 20:27 FC48-BF30 -> ../../sdb1 lrwxrwxrwx. 1 root root 10 2 dic 21:27 1D59-EB48 -> ../../sdc1 -- This message posted from opensolaris.org
