trage das oben erzeugte efi-image in die DHCP-Server config ein:

	class "UEFI-64-1" {
		match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00007";
		filename "grub/grubnetx64.efi.signed";
	}
	class "UEFI-64-2" {
		match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00008";
		filename "grub/grubnetx64.efi.signed";
	}
	class "UEFI-64-3" {
		match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00009";
		filename "grub/grubnetx64.efi.signed";
	}
