I have build an embedded Linux system and rootfs is a ramdisk. Ramdisk
rootfs resides in memory so modify files
-filesystems.pdf
depending on your requirements/size of the rootfs partitions UBIFS
might be an option to consider

AFAIK the mtd core doesn't permit changing a partition from ro to
rw. but if you happen to need to reflash the partition anyway, you can
load a tiny kernel modules that changes the flag indicating if a
partition is writable.
