Shouldn't it be RAMTYPE="<ramfs|ramdisk|auto>", where ramdisk stands for
the currents aproach with the ext2 file system and ramfs stands for the
ramfs/tmpfs/memfs method mentioned in that Linx-Kernel Archive eMail?

Still I'm not sure what exactly are the differences between
tmpfs/ramfs/memfs. Some observations:
- df -h does show a tmpfs "disk", but not one mounted with ramfs.
- a tmpfs file system has permissions like a /tmp directory: drwxrwxrwt
- My current working computer (PPC with a 2.6.6 kernel) does not want
to mount a tmpfs disk, but mounts ramfs. It says:
mount: wrong fs type, bad option, bad superblock on tmpfs,
or too many mounted file systems
- both of my computers don't know a memfs file system
Greetings,
