(Get the code!)
Sorry for the delay, we had a big outage last week which gobbled up most of my time.
I think the important part of the isc-dhcp-server config is the lease time. Making the lease time longer increases the impact of the bug. The default lease time (10 minutes) causes the VM to renew the lease after 5 minutes, now with the correct hostname. A long lease time (1 week) means that the DNS will be incorrect for multiple days.
So as a workaround, we've set the lease time on 5 minutes, which causes the clients to renew the lease after 2.5 minutes. This means that the DNS is fixed before Kubernetes is installed.
