I just use a Podman container to sandbox all the "closed-source / not from my distro's repo" software. https://news.ycombinator.com/item?id=34634584 https://news.ycombinator.com/item?id=34634584 Normally this is Ubuntu / Debian, but if I had TFA's specific problem of "I want the software to use my distro's /usr" I'd use a container with the base image of my distro. I don't bother sharing dbus, but if you did want to share (a subset of) it as TFA does, then yes xdg-dbus-proxy is a necessity.
