It probably depends on the BIOS, iirc, standard PXE does not support
anything other than tfpt, but you can probably configure the IP settings
manually, and I think the bios on the machine I was working with
supported https (but I am not 100% sure, and can't check at the moment).
iPXE supports https, of course, so we definitely want iPXE recipe and
documentation.

Yeah, but keep in mind that the stuff only happens 'in the image' when
you have already booted, so you can only script stuff to do with the
rootfs in the image; the kernel and initrd is loaded by the PXE
bootloader so the control here is whatever the PXE bootloader gives you.
