Aha! That explains it. I didn't read the logic in my copy, I just
did a quick search for the name to be hard-coded.

I'd say it's MAKDEV's bug in assuming that all kernel device names
follow shell naming rules. A better program would use a data
structure to store the names, rather than making them part of the code
itself. However, sh is not structured enough for that level of
abstraction so I understand why the current design is used.
I recommend that you file a bug against 'makedev' explaining the
this device-mapper thing and how that causes MAKEDEV to fail. At
least then there will be a record of this issue and the maintainer
will be aware of it.
