# This updates the host system.
# NOTE: This doesn't update the Anvil! software stack yet, just the OS.
#
# - On Striker; This will take the system offline and then run 'dnf -y update'.
# - On Nodes; This will do nothing until all servers are off the node. Then the node will be withdrawn,
# updated and then rejoin the cluster.
# - On DR; This will do nothing until no servers are running, then it will update the system.
#
# In all cases, the system will be rebooted if the kernel is updated.
#
# Exit codes;
# 0 = Normal exit.
# 1 = No database connections available.
# 2 = The job UUID was passed, but it wasn't valid.
# 3 = It looks like the update failed, reset progress to '0'.
#
# TODO:
# - Use this to update local repos for when we get to the Install Manifest stage.
