With iPXE on UEFI, the initrd _directive_ specifies where to fetch the initrd image, and the initrd _kernel argument_ tells the kernel where to find that image after iPXE has written it into the UEFI virtual filesystem. The initrd= argument isn't needed on BIOS but is harmless there. Fixes: #233 See also: https://ipxe.org/appnote/debian_preseed
