Very coolly. The main rc script runs a script named `rcorder' to
generate the proper order. rc.shutdown also uses `rcorder' but reverses
the ordering. Two examples are included below to show what `rcorder'
uses to generate the list. These NetBSD rc files also provide "start",
"stop", "restart", "status", etc. commands to assist the sysadmin.
Again, *very* slick and still quite BSD-like.
