muvm: Add a --passt-args argument to pass args to passt by valpackett · Pull Request #224 · AsahiLinux/muvm

Sometimes it's necessary to pass additional args (such as the network interface) to passt. It's already been possible to spawn passt externally and give muvm its socket, but that's inconvenient especially when one wants to keep using the nicer muvm syntax for the exposed ports.

Thinking of it, how bad would it be to instead do args "compiler driver"-style, so everything preceded by, say, -P gets sent to passt, and we do not do any shell expansion of our own? Eg: -P --tcp-ports -P 22

I think that would only make sense if we expect that passing passt-args would be a common usage?

Opposite, actually, this simplifies word splitting and does not need pulling in an extra crate in exchange for a slightly less convenient syntax

IMO short names are a very limited resource.

Well we coooould do that style with a long arg, I guess xD
