swaplabel [-L label] [-U UUID] device
swaplabel will display or change the label or UUID of a swap partition
located on device (or regular file).
If the optional arguments -L and -U are not given, swaplabel will sim-
ply display the current swap-area label and UUID of device.
If an optional argument is present, then swaplabel will change the
