# This program will disable our daemons on all machines, then update each striker. It then walks through all
# DR hosts and Anvil! nodes. With nodes, it migrates servers to the peer, takes the node out of the cluster,
# updates it, reboots if the kernel was updated, and then rejoins the cluster, migrates the VMs and the does
# the same process on the peer sub-node.
#
# Exit codes;
# 0 = Normal exit.
# 1 = No database connection.
