How do i get RD2 (aarch64) to let me run amd64 binaries?

I guess we don't have support for enabling Rosetta yet. You can use QEMU with something like this:

docker run --privileged --rm tonistiigi/binfmt --install amd64

You will have to re-run this after each start of the VM because the handler is only installed in memory.

I think I tried that. It didn't seem to result in things doing quite what I wanted and I can't figure out why. Fwiw, I'd like to see a button next to the Rosetta button for the equivalent of this. I don't think I want to install Rosetta
