Ramfs is not a filesystem for use on a block device, it's a virtual
filesystem that only lives in memory. It doesn't need any mkfs, you
just mount it and it's ready for use: mount -t ramfs none /mnt . Ramfs
allocates memory on the fly.

A ramdisk is a block device that lives in memory which you can format
with whatever filesystem you like. It has a fixed size independent on
the amount of files you store on it.
