Non of this requires 'dependency information' to be inserted as comment
block into a script supposed to start or stop something (that this
effectively means 'init.d commands' must be implemented in languages
supporting #-comments was probably another unintended side effect of
this "Houston, we have a file! Can't we put some more stuff into it?"
approach).

Continue the fine practice of uniformly starting and stopping everything
at a default policy of "20", IOW, in parallell. Software is supposed to
solve technical problems, not to work around people's mental
deficiencies (such as the inability to understand that 'X was true a
second ago' doesn't imply anything about 'X' right now or at any other
time in future).

NB: I suggest that anyone who believes that I made this up spends some
time observing movements of people in the street, specifically, how
often they run (or almost run) into things because they assumed them to
be static while they were actually moving. This is a really common
trait.

I consider this a much better idea for implementing such a system.
