You can add custom repositories to mock (just add them to the relevant
file in /etc/mock/<dist>.cfg).
Then create your own mini-repository with the two missing packages,
cp .../fakechroot-2.9-1*.rpm .../febootstrap-1.5-1*.rpm .
and add the path to my-repo to the mock config as a custom repository.

Yes - it's something I'm going to try to get to this week. I'll
follow up with the BZs once I've done them.
Actually, I'm not certain what the status is of fakechroot 2.9 +
patches, so that also needs looking into.

It's only temporary. This needs to go into rawhide proper, and I
think there is still one patch waiting on approval from upstream, so
that's something to check this week.

Well, you'll need to change the code. See daemon/configure.ac and
What was the problem with just installing augeas-devel? It's in
Fedora 10 updates & Rawhide.

Yes, good idea!
Have a look at how the guestfish alloc command is implemented.

Ok - probably something to discuss with qemu and/or KVM upstream.
