It's probably worth mentioning that this is basically the path down which
OpenRC went, except that OpenRC has taken the concept somewhat further to
allow the dependencies to be specified in code instead of comments (using
special shell functions). You may want to take a look at their syntax,
since it's extremely close to what you're doing but possibly a bit more
