     Adam proposed that the renaming happens in a different namespace so 
as to not clash with kernel naming new interfaces asynchronously. At 
this stage of the thread, the necessity of interface renaming was not 
yet questioned; at least this mail of Adam was not an opinion on wether 
renaming was necessary/useful or not.

     I suggested that renaming was not a necessity and the same method 
could be used to refer to network interfaces as was used to refer to 
partitions, since the problem of device name inpredictibility is exactly 
the same.
