With Fedora 39 (util-linux-core-2.39.2-1.fc39), the mount command starts to fail. It was still working with Fedora 38 (util-linux-core-2.38.1-4.fc38). $ unshare -f -p -m --mount-proc -U --map-root-user -n bash -c 'mount -t tmpfs --make-private /var/run && mount' mount: /run: mount failed: Invalid argument. Not sure why this starts to fail. But arguably the command line arguments were wrong. Fix it, we need a pseudo name for the device.
