I wonder if these can easily run linux AMIs. Since OSX doesn't have native containerization, our CI system for mac builds runs linux on mac minis and runs osx VMs inside of linux since you're allowed to run osx vms on linux if linux is running on mac hardware. So in an ideal world, we'd run our own linux AMI on the baremetal mac instances and run OSX in VMs.

I'm sure it's possible of course, but I wonder how painful it would be to setup. Fighting EFI/secureboot? Some other bootloader?
