We're using the offical Debian Stretch AMI.
Doing some investigation, it's clear that some hardening and optimizations have been done specific to the AMI for AWS/EC2 use.
How can I find out the specifics of what's been included/excluded in this AMI? (Is there a clear channel to communicate this question w/ the Debian team, or is the information is out there? If this was simply a community AMI I wouldn't expect much, but since it's from Debian, I'd hope some documentation is floating around).
Note: I'd like to avoid scripting our own AMI for now. And clearly some time, effort, and hardening has been put into this Debian AMI, and it'd be great to know what all went into it.
