What do you believe we want this for? Cluster machines have a static IP.
For laptops with a dynamic IP, it’s more correct for their hostname to
resolve to 127.0.1.1, so that loopback connections don’t break every time
the machine goes off the network. (And we shouldn’t fiddle with the
network config of non-cluster machines, especially if it ain’t broke.)
