 ## Use Cases
 
-### `systemd`
-
-A potential way of operating `ebs-bootstrap` is through a `systemd` service. This is so we can configure it as a `oneshot` service type that executes after the file system is ready and `clout-init.service` writes any config files to disk. The latter is essential as `ebs-bootstrap` consumes a config file that is located at `/etc/ebs-boostrap/config.yml` by default. 
-
-`ExecStopPost=-...` can point towards a script that is executed when the `ebs-bootstrap` service exits on either success or failure. This is a suitable place to include logic to notify an individual that the configured devices failed their relevant healthchecks and the underlying application failed to launch in the process.

-It is then possible to configure another `systemd` service to only start if the `ebs-bootstrap` service is successful. Certain databases support the ability to spread database chunks across multiple devices that need to be mounted to pre-defined directories with the correct ownership and permissions.
-
-In this particular use-case, the database could be configured as a `systemd` service that relies on the `ebs-bootstrap.service` to succeed before attempting to start. This can be achieved by specifiying `ebs-boostrap.service` as a dependency in the `Requires=` and `After=` parameters.

 ### `cloud-init`
 
 By default, `ebs-bootstrap` consumes a configuration file located at `/etc/ebs-boostrap/config.yml`. `cloud-init` can be configured to write a config to this location, using the `write_files` module. Ensure that `ebs-bootstrap` is installed on your Instance via the process of baking it into your Golden AMI or downloading it early in the boot process, using the `bootcmd` module.
