Yes, any reusable system will need to support additional system packages
and ./configure flags and so on.

Right -- the key to this working well is that no switch should be
necessary.  Written properly, you add one 'include' to your existing job
definition file and that enable opt-in functionality.

I'm also quite merried to the job definition files I have so it will
take time to surrender them, but I also realize that large chunks of the
files I have repeat a lot of the same code patterns.

It's an experiment, I'm not sure how well it will work out, having
started on this a couple of times before and failed...
