Bare metal support

[GrabbenD]

Absolutely love the idea of scripting the installation of my distro though docker.
This could especially be useful when attempting to run a immutable base distro which uses containers for applications.
Bare metal support would be highly appreciated!

@GrabbenD Thank you for your interest in the project 😀 !

We don't have the infrastructure to test d2vm on bare-metal.

Perhaps this is already possible with raw mode. We need to be able to test it.

If it works in raw mode, we could either detect whether a kernel is already installed beforehand so as not to add the kernel optimised for virtual machines, or add an option to choose the kernel flavour.
