# Related to https://bugs.gentoo.org/396467
# How to use:
# * Download undionly.kpxe or ipxe.usb from http://boot.ipxe.org
# * replace any pxelinux.0 with undionly.kpxe, or even better configure dhcpd to point to undionly.kpxe
# * setup http server hosting this and the below files (http is faster then tftp)
# * PXE boot a machine (or use usb image), and you should see iPXE start and a prompt for pressing Ctrl-B - do so
# * dhcp - to get ip
# * chain http://gentoo.ipxe.se/boot.ipxe - (this file) to boot
# please use discussions on https://github.com/NiKiZe/Gentoo-iPXE for questions

# Download the squashfs image, iPXE adds CPIO header so that it is appended to the initramfs above
# this makes it exist in the booted system
# the second argument /image.squashfs is name of file inside cpio
initrd image.squashfs /image.squashfs

# Let's see what we got

# boot the currently selected image (it was selected by the kernel line)
