Subject: scripts: ubinize-image: make rootfs optional
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5a305e429facce7fae71f5589b4adbb55b918c9c;p=openwrt%2Fstaging%2Fthess.git

scripts: ubinize-image: make rootfs optional

Currently ubinize-image script always expects the
rootfs image to be passed and a volume for it created.

So, to allow only ubinizing a kernel for example which
the MikroTik hAP ac3 and other new NAND devices from
MikroTik require make rootfs an optional parameter like
kernel.
