Subject: burn: Fail if no arguments are provided
X-Git-Tag: v25~97

burn: Fail if no arguments are provided

If no arguments are provided systemd-repart will operate on the
device backing the rootfs which in the case of burn we definitely
don't want to do most of the time so let's fail unless a device is
explicitly provided.
