Did they really? I'm guessing this is a BSD of some kind? Or have they actually built their own kernel from scratch? I kinda doubt it, and it was hard to tell, even their GitHub readme.md is just marketing material, not the tech specifics for Devs I'm used to finding there.

But to answer your question, umbrelOS is debian. You're right that they don't advertise that fact anywhere (that I've seen). They use rugpi to build a preconfigured image that includes their changes and their software. All the details are indeed public and open, if you know what you're looking for:

Half of the IT team I am on is seemingly incapable of understanding using a public/private keypair for SSH logins.
Can I use yours? How to copy them? Should they be unique per user? Should I email the private key? Etc?

No. Just no. That key is forever unclean.
