I have opted to build images a bit differently, not using the stuff in src/release. I’ve done two approaches.

The first is to attach a second disk to an EC2 instance, install FreeBSD onto it with customizations, and then image the disk (https://gist.github.com/patmaddox/9f20edcb50ff15fa9edd1d4e38d07e50).

The way I’m doing it now is to use poudriere to make an img file, and then upload that image to S3, snapshot it (aws ec2 import-snapshot –disk-container Format=raw,Url=s3://mybucket/myimage.img) and finally make an AMI from that snapshot.

The stuff in src/release is good for knowing what changes to make to config files, or packages to install.
