I'm curious: is there a repository of scripts for producing a working ISO image from scratch? How does it work when you (the administrators/maintainers) prepare an ISO for a new release? I doubt the process is manual but I can't find the build scripts.
I would like to be able to build an ISO image myself and tweak the files in core.gz, specifically my goal is to update busybox and sudo to the latest versions using the official build flags.
If there isn't a repository, that's fine, but it would be great if you can point me to the place where I can find the build flags.
