	I have tried to use it. I have built a um-linux 2.4.26 kernel with
	the last OFS-2 VFS. I can boot um-linux with a Woody root image.

(none):/# cat /proc/filesystems 
nodev   rootfs
nodev   bdev
nodev   proc
nodev   sockfs
nodev   tmpfs
nodev   shm
nodev   pipefs
nodev   binfmt_misc
        ods2
		ext2
nodev   ramfs
		iso9660
nodev   nfs
nodev   devpts
nodev   hostfs
nodev   humfs
nodev   hppfs
(none):/# 

	Thus, the ODS-2 driver is available. But I cannot mount c.img (even
	I use losetup -o 32901120 /dev/loop0 c.img and ./linux
	ubd1=/dev/loop0. Any idea ?
