It's not explicitly used -- it's just a name that sorts near the
beginning.  To be more explicit:  when the sorting takes place,
the directory name is included along with the unit name, so
sorts before

Yup, that's the only place it's documented.

Yes, something like that would be appropriate -- or use the sorting
already determined by metaconfig for the shell portions of the units.  As
it says in README, however,

	This could be fixed, I suppose, but it wasn't trivial the one
	time I looked.
