I can't recall for sure, but I think OP is concerned about LABELing the
swap partition. A swap partition is NOT an extN formatted region of
the block-special device. e2label fails to find a superblock on a swap
partition on my jessie machine and I'm not a bit surprised at learning
that ;-O

Also blkid displays a "PARTUUID" in addition to the familiar UUID for
all the partitions on the internal hard drive on my jessie machine.
This "PARTUUID" has fewer hex digits than a the 'real' UUID. It looks
as if there is a lot of new conventional to be learn by people who
have learned on Linux internals long ago. Or maybe I'm the last to
learn about this innovation.
