Hi, sorry, I do not understand the problem. First of all, I never ran
this on a device which uses an UBIFS file-system as rootfs. I only ran
it on a PC where UBIFS has only been on top of a nandsim.
So, AFAICS, power cut emulation is per-mountpoint. So you should enable
it only for the the file-system under test. Power-cut should switch only
the file-system under test to R/O mode, not the rootfs.
What are the practical problems you mention?
