the compressed cramfs image will be loaded into ram, and then, from
there, as pages are needed, they will be decompressed again and put into
ram (but again, if memory is in a pinch, these pages can be dropped). I
don't know if an ext2 initrd will do XIP (execute in place), but I
somehow doubt that anyone has worked on that, meaning that the pages
would need to be copied again, in which case, a cramfs would use less
ram.
