I needed to install qemu-user-static on podman running on macOS to enable [multiarch build](https://zozoo.io/run-a-multiarch-build-using-podman/) of Docker images. Assuming you already have `brew install podman` and `podman machine start`, how do you install a package? $ podman machine ssh $ sudo su - # rpm-ostree install --reboot --idempotent qemu-user-static I used the `--reboot` flag because that's what the aforementioned blog post instructed, i.e. reboot the VM.
