My intent is to have a trail of crumbs when the expected events fail to happen.
If the boot sequence gets to runlevel 2 that is very different from
  runlevel unknown . The OS may be up, at it could be argued that it is not
running properly. It would be nice if it said so.

Maybe there should be a final *.conf that says

        assert event foo has happened
        assert runlevel 2
        assert mount /home
                :

A console and/or log entry of the form
        /etc/init/glurp.conf: failed: no required event foo
would be very useful, whether that failure was severe or just unfortunate.

A further analysis of
        /etc/init/glurp.conf: required event foo: no emit found
would also help.

A stanza of the form
        start on required foo from /etc/init/whiz.conf
might yield
        /etc/init/glurp.conf: /etc/init/whiz.conf: not found
   or
        /etc/init/glurp.conf: /etc/init/whiz.conf: does not emit foo

Agreed. But at least it complains. The recent problems have been boot
sequences that _appear_ to be complete but in fact are not.
