I’m not 100% sure as I didn’t create the image (though I’m evangelizing as someone who has found it truly helpful for daily dev.) . I believe the creators tarball’d the entire distro/execution environment from a running lambda so the file system layout and libs likely match Amazon Linux if that’s the default lambda execution distro image. If not I assume it matches the default
I saw that the SAM CLI uses an Alpine based image, does yours use Amazon Linux 2?
I'm jusz asking, because I compiled some libs on Cloud9 (which uses AL) and they worked on Lambda, so I assumed it's the same dist.
