Nice!  Documentation will be welcome.  :-)

In this context I think ‘httpd-’ would be good enough as a prefix.

I think having this list here is the right approach.  However could you
write where it comes from?  I guess it’s equal to the current default in
httpd, right?

How often do you expect this to be updated?

Or “loaded-modules” or just “modules”?

I wonder if we could abstract ‘run-nginx-test’ just enough so it can be
used for both.  It’d need to take a service name, log file, and PID file
as arguments.

Otherwise LGTM, thanks!
