Shouldn't it be (98, 16) then, if ubd0 is (98, 0)?
Indeed, mounting works perfectly with /dev/ubd16 and /dev/udb17.

The HOWTO at http://user-mode-linux.sourceforge.net/UserModeLinux-HOWTO
does not seem to include the current maintainer's name nor email (how
modest). I think it would be nice if this tip made it into the section
about "Creating filesystems"...

Thanks, Jeff!
