This is a read-only filesystem.

Mount the cramfs image on a local system to get the individual
files/directories, say in /home/foo/image. Copy the image/ directory
to a new directory, say, /home/foo/ramdimage.

Let us say we want to create a 3 MB ext2 ramdisk image. Use the following:

  dd if=/dev/zero of=/dev/ram4 bs=1k count=3072
  mke2fs -vm0 /dev/ram4 3072
  mount -t ext2 /dev/ram4 /home/foo/ramdimage

Modify the contents of /home/foo/ramdimage for your requirements.
Create a new ramdisk image:

  dd if=/dev/ram4 of=ramdisk.img bs=1k count=3072

Compress the ramdisk image using gzip, and use it.
