Yes nice. Just looking into it. "Rather than providing random binaries of RattlesnakeOS to install on your phone, I've gone the route of creating a cross platform tool, rattlesnakeos-stack, that provisions a "stack", which is just all of the AWS cloud infrastructure needed to continuously build your own personal RattlesnakeOS, with your own signing keys, and your own OTA updates. It uses AWS Lambda to provision EC2 spot instances that build RattlesnakeOS and upload artifacts to S3. Resulting OS builds are configured to receive over the air updates from this environment. It only costs a few dollars a month to run (see FAQ for detailed cost breakdown)." Wouldn't this make sense for GrapheneOS? I assume in development you don't rebuild everything from zero just you changes but not sure?
