Configuring PXE for Multi-arch
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If the environment consists of bare metals with different architectures,
normally different ramdisks are required for each architecture. The grub
built-in variable `grub_cpu`_ could be used to locate the correct config
file for each of them.
.. _grub_cpu: https://www.gnu.org/software/grub/manual/grub/html_node/grub_005fcpu.html
For example, setup ``$TFTPROOT/EFI/BOOT/grub.cfg`` as following::
set default=master
set timeout=5
set hidden_timeout_quiet=false
menuentry "master" {
configfile /tftpboot/grub-${grub_cpu}.cfg
}
Prepare specific grub config for each existing architectures, e.g.
``grub-arm64.cfg`` for ARM64 and ``grub-i386.cfg`` for x86.
Update dnsmasq configuration to contain options for supported architectures.
