This had certainly crossed my mind too, but for reasons already
suggested, it doesn't seem the right thing to do. I'm not convinced
that libutil is the right place for such code either - it's not
useful enough to appear in a fairly widely-used library.

Two other not-so-elegant approaches are:

- Share a source file between reboot and init.

- Make reboot(8) and halt(8) hard links to init(8), and have init
  do the right thing according to argv[0].
