 CHECKPOINT_DISABLE=1 packer build 
 ```
 
+In the Debian package, this behavior is swapped so that the service is disabled
+by default, and only enabled with an explicit `CHECKPOINT_ENABLE=1` due to DFSG
+compliance.

 **Note:** This repository is probably useless outside of internal HashiCorp
 use. It is open source for disclosure and because our open source projects
 must be able to link to it.
