Ah. Primarily, building in a VM as opposed to a chroot. Secondly, the image
preparation would run on the _host_ system's OS, rather than the
to-be-installed one, so fixes to the image generation would have to happen
at that level rather than in the tree. (The installer itself matches the
installation, but the infrastructure firing up the VM and processing the
output might not.)

There _are_ issues to solve but I think it pretty much has to be the way
forward, because building in a chroot, _especially_ with a tool other than
anaconda itself, has its own set of issues. 

Using something like livemedia-creator or oz has enough advantages that it's
worth spending the effort to fix the difficulties. Jay Greguske is working
on integrating this into Koji, but, yeah, too much work to make F19.
(Initially for cloud images, but eventually doing live images the same way.)
Some kind of combined approach might be possible. (Especially when we have
nested KVM on the builders....)

I was just wondering if there were other potential pitfalls to be aware of.
