Just gonna bump this again. Would be great to see support for this as it would be super helpful for complex architecture-based netboot configurations.

Happened across this one while trying to find support for defining client classes in Kea in order to pass different PXE boot files depending on client architecture. The following has an example of how this is achieved in kea.

I went ahead and dug out the other configuration that doesn't work in 1.2.0 either. This is pulled from the config.boot file in the vyos 1.2.0 image i have installed.

I have included the requested configs (some portions of configs have been censored for security purposes). I have since rolled back to 1.1.8 for this and other reasons but I can confirm that this configuration works on 1.1.8 but not on 1.2.0.

I checked the 'server' options for 'push-route' and 'name-server' and even with these configured as opposed to the openvpn-option configuration entry, it still gives the "Options error" complaint about the push command.
