I think that's very well a quite bad bug, when make-fai-nfsroot deletes 
all the nfsroot including the contents of the still mounted mirror!

Depending on where you  are, it can very well be catastrophic, as not 
everywhere is an >10Mbit download link...

Because it's a bug,  guess. I also guess, that the nfs mounting of the 
mirror simply is not used so very much - as using an ftp apt mirror is 
simpler - and when this is configured it can also easier later be used 
by the installed systems.
