Among with the device tree syncing, these are the things I really want
to get rid of, especially drivers as today they do not support IOMMU so
I will also have to implement that as well.
I guess I could write a small firmware which would read MBR/GPT, find
PReP, load GRUB elf and jump into it (although this seems unnecessary
complicated for the task and definitely duplicates the code) but having
drivers in what is defined as a driverless environment is just weird imho.
However I am struggling with hooking network from CI to the network
backend, not as easy as blockdev, need another temporary netclient :)
