[Leaplist] fstab

[Aaron Morrison]

e2label will be the program you are looking for.

e.g. To see what a partition has been labeled.

# e2label /dev/sda1
/boot

To set that to something else
# e2label /dev/sda1 MyLabel

# e2label /dev/sda1
MyLabel

Don't forget to update the fstab and grub conf file if you do change  
the label of "important" partitions.
