Your jffs2 question was already answered.

But this one wasn't answered:

> What about cramfs?

You can in fact use cramfs "on a ramdisk", e.g.:

cat image.cramfs > /dev/ram1
mkdir /mnt/cramfs
mount -oro /dev/ram1 /mnt/cramfs
mount | grep ram1
/dev/ram1 on /mnt/cramfs type cramfs (ro)

Of course cramfs also works on other block devices as well, e.g. mtdblock.
