Most of what I've had to say about wedges has been addressed well
enough by others, but I do have one concern: one of the messages wrote
of forbidding overlapping wedges (except for parent/child overlap, when
a real wedge hierarchy exists).

I think that would be a very bad idea.  I have found far too many uses
for overlapping partitions for me to see forbidding wedge overlap as
anything but a huge step backwards.

Long ago, I added code to newfs to make it work without DIOCGDLABEL if
the appropriate geometry options are given on the command line.  (I did
this primarily so it would support newfsing a file containing a
filesystem image without having to attach it to a vnd and give it a
label for the purpose, but it would also serve this end.)  Any interest
in picking up those changes?
