# 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
OS="$1"
echo "Add SSH public key for root user"
# We don't use 'ssh-copy-id' because it requires the machine to be
# running and available over SSH already. Luckily the manual case is
# simple.
mkdir -p "$OS/root/.ssh"
target="$OS/root/.ssh/authorized_keys"
echo "# Added by Baserock root-ssh-authorized-key.configure" >> "$target"
cat "$ROOT_SSH_PUBKEY" >> "$target"
