Would be nice if we had a github action to run the spec tests and include them in PR's. Let me know if ya'll are interested in that and I can submit another PR.

This code looks reasonable, though I admit I don't fully grok this codebase.

But merging without tests seems scary, so yes, if yo'ud be willing to make a PR to add GH test for the specs that'd be great. Thanks!

Looks like chef/mixlib-shellout relies on buildkite for that info. Not sure if folks want to plug into that or if a GH action would be preferred. Do we want to include that in this PR or should I do another?

My instinct prefers the GitHub Actions route, but I'm willing to be convinced otherwise if that route has roadblocks with this code base.

I also prefer Actions. You can see chef/chef for an example. However, some stuff may only be available in buildkite, feel free to copy-paste that stuff if necessary. Definitely a separate PR, please.

Screwed up my branches (commited this main). #90 is the new PR. My bad!
