Buy DVDs and rip them?

My recommendation (sorry for the delay in response) would be not to use it as a base. Use the image as such. It has in-built features for screenshots, for using puppeteer, etc. So just use those. Any issues with that approach?

Try using this following project as your base image before throwing puppeteer on it (or use the inbuilt functionality to take screenshots). It includes Jessie Frazelle’s seccomp profile. If you want nightmares, go read her blogpost about it. Otherwise just let it be and follow the setup guide in the readme of this project -
