As I wrote in my previous mail, I think a new parameter for the ubiblock
tool would do the job.
I'd default ubiblock to RO and via the ubiblock tool you can enable RW mode.
...which would also trigger a warning.

What I'd like to avoid is a kernel command line or a Kconfig option to make
RW default. If someone *really* wants RW she has to run ubiblock --enable-rw....
in userspace. This should even work for block filesystems on top of UBI
as root fs as you can remount them later RW.

Sounds like a plan?

Thanks,
