Additionally, I decided that it would be useful to store the computer’s Company Asset Number in nvram, and make that available in grains.
To solve this, I made some customized grains and made them available on GitHub.
If you want to know how to use the customized grains, check out the wiki.
If you have issues with the custom grains, please use the issue tracker.
General questions and comments can be made here and I’ll get to them as I can.
