That's what I told you in the previous mail, removing the rootfs=

mount a ubi device (which is a character device in Linux) with a
block-based filesystem (like squashfs). This cannot and won't ever
work and you could either leave it to OpenWrt/LEDE's auto-probing to
figure out what to do based on the rootfs type (non-ubifs vs. ubifs)
or append even more board- and filesystem-specific crap to your cmdline
such as ubiblock=... root=/dev/ubiblock0_1 (however, that then won't
work for ubifs, thus the auto-probing patches).
... OH!
Well, I needed some extra intellectual clubbing to catch on.
NOW I remember reading the UBI docs, about glubi, the fact that volumes
are char devices, and I even seem to remember some ALL CAPS red size-20+
text at the top of the page saying something about it.
Tomorrow I'll go read the docs again, because I know I remember reading
that you could put a RO-squashfs in a UBI volume. I just need to have
it mounted the right way.
