more specific example: you can use apache without mysql, and you can
use mysql without apache, but quite often they are used together, and
if so you likely want to start mysql first, and apache second, since
it likely consumes services of mysql, and not the other way
round. Hence in this example, you'd place an ordering dep, but not
requirement dep.
Would such an ordering dependency without a requirements dependency allow
apache to start without mysql? Or does an ordering dependency imply a
requirements dependency? In which case, could systemd automatically infer
the requirements from the ordering?
