I really like this. Then we don't need a separate canonical location
for 'LNG' because we only update the install images in 'rawhide' if they
have gone through some level of sanity testing?'
Would there be any downside to continuing to do this even after NFR is
an established part of our process?

If you want to propose these dates (see other schedule) email I can put
them in now so we have a working draft to discuss at FUDCon.
