In practice, the entries here are mostly static already - the only
time that something gets added there is when a new class of machines
gets added.

As I say, the only time that these entries get touched is when a new
class of machines gets added - and given that people can't read (proven
by the number of times people get their entries out of order), they
should come through my tree.

Actually, it'll increase the chances of a conflict when a change is made
to it - because more machine classes will be visible to any particular
patch.  If we have two similarly named machine classes added at the same

I think you're trying to make a mountain out of a mole hill.  This
hasn't been a problem to date.
