Hi all, following up on a quick discussion with Stefano on IRC. passt/pasta currently rejects most (not all) options when specified multiple times, i.e. pasta -I eth0 -I eth1 ... fails. I think it makes more sense to just use the last one instead. My use case: In podman I added a new containers.conf option[1] which allows users to set default pasta cli options. However users can also add options on the podman cli with podman run --net=pasta:... For me it would make the most sense to just append those to the config options and then let pasta deal with it. This allows some form of overwrite mechanism, i.e. by default I may have "-I" , "eth0" in containers.conf but for one specific container I want to use a different interface name and set --net=pasta:-I,eth1 on the cli. Then podman should just hand "-I eth0 -I eth1" to pasta and then pasta picks the last one. If we keep the current behavior it means I am forced to parse the options in podman and dedup them which is hard to maintain as podman would need to keep up with pasta upstream. I am willing to send a patch to change this so please let me know if anyone would object to that. [1] https://github.com/containers/common/commit/da3ac5d6d025f2933e655a0541eddbc… Thanks, Paul
