New ipxe snapshot

[Comment 2 Joakim Tjernlund 2018-01-25 15:48:33 UTC]

This ebuild has some changes:

build efi like upstream - wont work for me otherwise

ARCH is hardcoded to x86_64 as I don't know how to do this properly

Adds IPXE_EMBED wich should point a ipxe script which will
be built in to ipxe

installs ipxe.lkrn to /boot for grub to use

example grub2 conf(/etc/grub.d/20_ipxe)
#!/bin/sh
set -e

if [ -f /usr/share/grub/grub-mkconfig_lib ]; then
  . /usr/share/grub/grub-mkconfig_lib
  LX=linux16
else
  # no grub file, so we notify and exit gracefully
  echo "Cannot find grub config file, exiting." >&2
  exit 0
fi

# We can't cope with loop-mounted devices here.
case ${GRUB_DEVICE_BOOT} in
  /dev/loop/*|/dev/loop[0-9]) exit 0 ;;
esac

# iPXE is only supported on x86
case $(dpkg --print-architecture) in
	*i386|*amd64) ;;
	*) exit 0 ;;
esac

prepare_boot_cache="$(prepare_grub_to_access_device ${GRUB_DEVICE_BOOT} | sed -e "s/^/\t/")"

IPXE=/boot/ipxe.lkrn

if test -e "$IPXE" ; then
  IPXEPATH=$( make_system_path_relative_to_its_root "$IPXE" )
  echo "Found iPXE image: $IPXEPATH" >&2
  cat << EOF
menuentry "Network boot (iPXE)" --users "" --class network {
${prepare_boot_cache}
    $LX $IPXEPATH
}
EOF
fi

Example script:

#!ipxe
ifconf --configurator dhcp || shell
chain tftp://my.installhost.com/install.ipxe
echo chain failed!
shell

I have created a new ipxe snapshot. However, it does not contain your changes for imbedding a custom script.

The new ebuild is now EAPI 6, it thus supports epatch_user. What about you create a custom patch for your own needs (that adds the script)?
