I'm standing up a new OPNSense for some blog posts and tutorials, and I realized that either the defaults have changed over time or I configured a bunch of things that I don't recall doing. :)
Looking through the repo there doesn't seem to be a default config that I can find and generally only deviation from the default settings show up in the config. Which means that even if I stand up a clean install, download it's config and diff it against a backup from my instance, I'll only see some of the changes.
Is there any way to get a true diff against the defaults, even if it's a manual process? This could also help in identifying obviated changes due to updates, etc.
