In general a good splitting for rootfs could be: squashfs for rootfs,
tmpfs for volatile data (/tmp), ubifs (with a flash partition) for
"strong" permanent data (/etc, ....) and pramfs for "light" permanent
data (/var/log, .....).
I think you should "split" your rootfs. Ramdisk is an old approach
with some drawbacks.
