UMSDOS is a hideous system.  I'm currently working on code which will
allow Linux to drop support for it altogether.  Basically, it's far
superior to use a file on an MS-DOS filesystem as a device on which you
create an ext2 filesystem.  Hopefully I can sneak this code in under
the 2.1 codefreeze (since UMSDOS has major problems in the development
kernels) but I've been far too busy recently.

UMSDOS: Just Say No.
