Comment 10 for bug 1823790

I carried out the following test:

* fetched the QEMU coming with 18.04,
* added this patch,
* built an LXD container with arch arm64 and the patched qemu-aarch64-static inside,
* launched it on amd64

Previously various systemd services would not come up properly, now they are running like a charm. The only grief I have is that network configuration does not work, but that is due to

    # ip addr
    Unsupported setsockopt level=270 optname=11

which is a different story.
