Just a quick thought. These days you can create a special partition in the first part of your drive and just boot from it. No grub, no config really. You might want to take a look at EFI and an EFI system partition perhaps?

I would also say this. Njalla is good

Tailscale maybe? They have a mode where you can configure a site to site links, you could route the docker networks. https://tailscale.com/kb/1019/subnets

In case you haven’t seen it already - 3mdeb shared some info on the state of things during last FOSDEM. If I’m not mistaken they also did an update the year before too.

I know of exactly 1 AMD corebooot laptop. Starlabs Starfighter.

For coreboot you’re basically on Intel. As others mentioned, look up dasharo. They have added support for two modern MSI motherboards and Intel cpu models.

Very well written article, very much worth a read.
