Well you've got to get it. Google is running on a 2.x Linux kernel, with thousands of patches. The hypervisor runs on bare-metal, and it's not "debian". You need to start thinking about debian as just another virtual system and get with the program. If you're installing an operating system on bare metal, and it's not a bsd with jails, you may be doing it wrong. Or, maybe you have an offline developer's environment bare-metal install, debian, arch, whatever, a linux efistub is enough, and then host a passed thru network vm, in a container, with strong guest to host protections. You do you?
