For this to work, I believe hostfs must be statically linked into UML
(unless there is some way to use an initrd type mechanism).  I build the
user-mode-linux package using the default kernel configuration, which builds
hostfs as a loadable module.  A copy of the kernel config is in
/usr/share/doc/user-mode-linux/config.gz:

CONFIG_HOSTFS=m

You can build a UML package with a different configuration by following the
instructions in /usr/share/doc/user-mode-linux/README.Debian.

uml-devel folks: is there a recommended configuration that I should use for
the Debian packages, other than the default?  Specifically, should hostfs be
compiled in?

Jeff: things have been going swimmingly with the official Debian packages
for UML.  Do you want to continue distributing separate Debian packages, or
use the official ones?
