    Make init set up a loopback network interface.
    
    This allows programs inside the UML to connect to each other via
    localhost network ports. In particular, this means you can do SSH port
    forwarding, or X11 over TCP, inside the UML.

    Make /dev/random really be /dev/urandom.
    
    Inside UML, there isn't a good source of entropy for the blocking
    /dev/random. So any program that tries to read it will unhelpfully
    block. And current advice is that you should almost always be using
    urandom anyway. So I think this is a generally useful change which
    makes things work that previously hung, and doesn't lose much.

    Mount a tmpfs on /run.
    
    This is a tmpfs even on the host system. In the guest, it should be a
    separate independent tmpfs.

    Bind-mount a replacement for /etc/hosts.
    
    Now we replace the host's /etc/hosts in the guest with a version that
    maps the interior hostname to 127.0.0.1 (in the absence of any better
    thing to map it to).

    Make /tmp/.X11-unix.
    
    If this directory exists, then Unix-domain X server sockets can be
    created inside it.
