Hello, we encountered a bug in the parameter parsing of mkfs after c&p of a wrongly written wiki article. So $ mkfs.ext4 -Llabel /dev/device and $ mkfs.ext4 -L label /dev/device work as expected. $ mkfs ext4 -Llabel /dev/device # note the missing "." reports correctly "invalid blocks '/dev/device' on device 'ext4'" after invoking mkfs.ext2 as the default mkfs. But when you enter the same wrong command line with an additional space in the label like $ mkfs ext4 -L label /dev/device it formats /dev/device with an ext2 filesystem and the label "label".
