Hi,

I downloaded a root file system from:
http://www.stearns.org/uml-root/root_fs.fc-4-base.pristine.20050622.bz2
and followed the instructions in
http://www.stearns.org/uml-root/root_fs.fc-4-base.pristine.20050622.note
in order to extract it. I am able to mount it as a loop device without
problems.
I applied the patch from
http://www.user-mode-linux.org/~blaisorblade/patches/guest/uml-2.6.13-bs2/uml-2.6.13-bs2.patch.bz2
to the 2.6.13 vanilla kernel and built a uml kernel with ext3 support not as
a module.
Now when I run it I get the following error:
