Unless the formatter is actually doing the disk partition initialization 
normally done by "mkfs", I can't see what difference it makes either.  As 
far as mkfs is concerned it just needs a disk partition map entry to find 
the physical space on disk allocated to the NetBSD partition(s).  With 
minor changes it can use *any* disk partition and scribble BSD FileSystem 
stuff all over it.  There are no flags or definitions in the Partition 
Map that specifically indicate the partition is an AU/X 2.0 or AU/X 3.0, 
just a flag that says it's an AU/X type partition.  Neither version of 
mkfs looks for an AU/X version number in the Partition Name field, and in 
fact the newest mkfs rewites the name to be something like "NetBSD Root & 
Usr" or "NetBSD Swap".

Maybe someone else can provide information on this AU/X version that 
explains what some people are seeing.
