Ah fair enough.  We don't cater well for that case at all right now.  We did 
assume it would not crop up very often but it seems that was an incorrect 
assumption.  Where it does happen we figured that someone could just do a 
regular upload so it wasn't a blocker, but I guess it'll get annoying.  
Perhaps we'll fix this in a future iteration on the feature.

This is for the OEM case, where they have a crazy-ass hierarchy of parent 
overlay distros! :)
