Of course there is one. Both ext2 and romfs do not compress each file,
you use compression on the whole image, and the kernel extracts the
beast into a ramdisk of the appropriate size. But files in cramfs are
compressed separated and extracted separated on the fly, so you do not
need the memory to hold the whole image. However, this is not important
for a modern system with >>16MB RAM.
