- make/change partition: gparted

- volume-label: 
(http://tldp.org/HOWTO/html_single/Partition/#volumelabels)
Volume labels make it possible for partitions to retain a consistent name 
regardless of where they are connected, and regardless of whatever else 
is connected. Labels are not mandatory for a linux volume. Each can be a 
maximum of 16 characters long.

There are three tools to make volume labels: 
mke2fs, tune2fs and e2label.

- e2label device [ new label ]


- devlabel 
is a script which creates symbolic links to devices. For example,

devlabel -d /dev/hdb1 -s /dev/home

will create a link from /dev/hdb1 to /dev/home. Crucially, it stores a 
unique identifier for the hardware that was on /dev/hdb1 and stores that 
identifier along with the link name that you specified in 
/etc/sysconfig/devlabel. If the hardware is later moved to /dev/hdc1, 
its unique identifier will be queried (using /usr/bin/partition_uuid), 
matched to its entry in /etc/sysconfig/devlabel, and again linked to 
/dev/home. 


- mlabel - make an MSDOS volume label
(http://linux.die.net/man/1/mlabel)

mlabel [-vcsn] [-N serial] drive:[new_label]

Mlabel displays the current volume label, if present. If new_label 
is not given, and if neither the c nor the s options are set, it 
prompts the user for a new volume label. To delete an existing 
volume label, press return at the prompt.

Reasonable care is taken to create a valid MS-DOS volume label. If 
an invalid label is specified, mlabel changes the label (and displays 
the new label if the verbose mode is set). Mlabel returns 0 on 
success or 1 on failure.

Mlabel supports the following options:
c          Clears an existing label, without prompting the user
s          Shows the existing label, without prompting the user.
n          Assigns a new (random) serial number to the disk
N serial   Sets the supplied serial number. The serial number should 
           be supplied as an 8 digit hexadecimal number, without spaces
