Since it occasionally happens, that a vyos setup must be moved to another machine, either virtual or bare metal, or network hardware might be exchanged for whatever reason, it would be great, if vyos could ask at boot-time or first ssh session login after boot to remap previously configured ethernet interfaces to other/newly found mac-addresses. This occurs when the interfaces are not configured in the config.boot file, or a configuration points to mac-addresses which are not present anymore. This behaviour would be preferred, instead of throwing errors or remapping the interfaces to macs without active admin interaction to choose which particular interface is to be mapped to a certain mac.

This would tremendously ease the pain of migrating a working setup to a different/new underlying machine and would make the config.boot file almost as much worth as a full machine backup. Of course special configuration like RSA-IDs or Wireguard keypairs are not included, but it would be of exceptional help.
