The two things that contain the master's identity are its IP address and a few different pieces of data from its local disk.

To make upgrades work on Google Compute Engine, we mount the four important directories listed below to a persistent disk and reserve the IP address of the VM, then detach the disk and IP and put them on a new VM. The directories saved are:

/var/etcd
/srv/kubernetes
/srv/sshproxy
/srv/salt-overlay
