+# This is a "morph deploy" configuration extension to add an SSH key as
+# an authorized key for the root account. This means that SSH access to
+# the machine as root is possible as soon as the machine boots, instead
+# of requiring an initial manual login. This functionality is used by
+# Baserock's automated tests.
+#
+# The following configuration variable should point at a file
+# containing an SSH public key: ROOT_SSH_PUBKEY
+
+set -eu

+# running and available over SSH already. Luckily the manual case is
+# simple.
