# Gentoo Syslinux test script
# Author: Maciej S. Szmigiero <mail@maciej.szmigiero.name>
#
# Requires:
# * sys-boot/syslinux
# * sys-fs/mtools
# * sys-fs/dosfstools
# * sys-block/parted
# * app-cdr/cdrtools
# * app-emulation/qemu
# * sys-firmware/edk2-ovmf
# * a qemu-bootable linux kernel image with a matching initrd image that
#   powers off the system when booted
#
#   For example kernel / initrd images based on Gentoo's install-amd64-minimal-20190417T214503Z.iso
#   please see https://gist.github.com/maciejsszmigiero/49dc6a74e711a917b24c2731963582a9
