A long time ago, in a galaxy not so far away,
the ironic comunity reached consensus that we
should refactor the PXE interface such that we
had separate PXE and iPXE interfaces.
In looking at what it would take for something like
a standalone deployment to have multiarchitecture
support in their environment, it seems even more
urgent and necessary that we begin to make this
delineation. This is because while some ARM iPXE
support exists, the binary is not a commonly
shipped artifiact, so operators are largely
only left with grubaa64.efi as their bootloader.
A similar issue exists with ppc64le deployments
where they must disable iPXE, as the ppc64le
hardware expects reading a syslinux compatible
file, similarlly no iPXE loader exists.
To start this effort, we need to promote iPXE
functionality to a dedicated interface,
and remove the necessity of setting the
[pxe]ipxe_enabled setting.
Next steps, beyond this patch, would be to
begin to tease out the common private method
code in the underlying PXE interface that both
the iPXE and PXE interfaces use, and appropriately
relocate and refactor that code as necesary.
During this process, we can create an [ipxe]
configuration section, and migrate settings.
Finally, once the deprecation cycle is complete,
we will be able to remove the ipxe logic with-in
the PXE interface.
