But there's a small difference:
mke2fs -L MyLabel /dev/sdn4
only sets/changes the label (ok - it tests the type of the partition and
refuses labeling if the type doesn't fit).
mkfs.btrfs -L MyLabel /dev/sdn4
not only sets/changes the label but also (re-)creates a btrfs
filesystem, using the default parameters.
I had to learn this difference ...
Viele Gruesse!
