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
appropriate value on device. These values can also be set during swap
creation using mkswap(8). The swaplabel utility allows to change the
label or UUID on an actively used swap device.
