Thanks for the responses all. I'm on Gentoo as well for what that matters. I think what i'm going to do (if i don't abandon EFI entirely) is just to get a small (16gb), $25 m.2 since my board supports that, and use that as my boot drive. Then mkfs other all discs to be partitionless and away i go.
Not sure what i'll use the extra 15g on that m.2 for. I learned a lot from your long response Chris. Thank you.
