My understanding is that UML runs a filesystem that lives within a particular 
file on the host system, rather than on a whole new linux system installed to 
a spare partition. 

For instance if you have downloaded a file called root_fs (from 
http://user-mode-linux.sourceforge.net/dl-sf.html) then you would start it 
with

linux udb0=/path/to/root_fs

hope this helps,
