immediately available on instances which are running without internet
access (or which can't rely on firstboot_pkgs to install it for some
other reason).
Note that this agent is not enabled by default; to enable it, add
amazon_ssm_agent_enable="YES" to /etc/rc.conf, e.g., by placing the lines
>>/etc/rc.conf
amazon_ssm_agent_enable="YES"
into the EC2 user-data. In addition to being enabled, the agent requires
keys to be provided via IAM Roles; users are encouraged to be very careful
in using this functionality due to the inherent vulnerability in the idea
of providing credentials via a service accessible to any process which can
open an HTTP connection.
