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.
