a "uRamdisk" can be in cpio format. Basically the "u" is just a
container for a ramdisk, and the ramdisk itself can use the cpio
format, or ext2, or whatever filesystem you want. However, by using
cpio, you leverage the initramfs mechanism of the kernel, which is much
better than initrd in terms of memory consumption.
See:
