Comment 4 for bug 1711710

This is no longer true. A dnsmasq interface was added, and ironic now generally sets/sends/uses option numbers. We also have OVN dhcp support working, albeit with Neutron doing option translation.

The base issue is the ipxe logic being required, which the server has to be aware of to support.

But operators are also able to choose based upon their state, it is just iPXE is never going to be a viable option if the DHCP server cannot be configured to convey the necessary configuration across, so if it is conntrail, and only PXE is possible, then there is also not much the project can realistically do given the constraints of iPXE.
