any counterpart of mke2fs for cramfs
I'm trying to build a cramfs filesystem. I have a little bit knowledge of building FS by using ramdisk. I've used etx2 FS for that and of used mke2fs for that.
How do I proceed for cramfs? There is 'mkcramfs' but that to 'cram' an already built FS. How do I build the FS in the first place. It's the counterpart of 'dd if=/mnt bs=1k | gzip -v9 > rootfs.gz'.
I've heard that cramfs doesn't require a ramdisk to be built. How do I begin then?
