This will break things if rootfs is a read-write UBIFS volume which should
by dynamic. I also saw weird things happening when trying to access static
volumes in U-Boot and thus avoided them for now.
Please also consider that ubootenv* and kernel could be static volumes as
well, however, that needs to be tested with a more recent U-Boot (I hope
it'll work).
