This is concerning and may cause problems later on. One possible factor
here is SELINUX. Do you have that enabled? We've tried to ensure the
system works with SELINUX but the policay may vary quite a bit from
Fedora 12 to 14 (where I know a build with SELINUX has run).

Pseudo is akin to fakeroot, so it allows us to set appropriate
permissions for the generated image without requiring root privileges on
the build machine.

That is how we intend to operate but I know we have had issues with host
contamination in the past and may well again in the future. We have the
beginnings of some machinery in place to catch these issues earlier,
however.
