A main difference if I understand, is that mfs uses a backend closer to
a disk file system and can also be tied to kernel images using
mdsetimage.  mfs also has size restrictions defined at configuration

tmpfs on the other hand might theoretically grow in size more
gracefully and provide enhanced performance, but I honestly didn't try
tmpfs much myself...
