I believe Debian has official distro packages now. Arch, gentoo and NixOS certainly do, but they're often a release or two behind. AMD only provides packages for the big corporate distros (Ubuntu, RHEL, SUSE), which I guess is fine. The odd one out is Fedora. There are official distro packages, but only for rocm-opencl, not for the whole stack. But ROCm is open source, so in the spirit of open source software, I believe distros should handle packaging duties. Only the distro maintainers know how they want to to compile, distribute and package the stack.

This isn't the opposite direction, copyright isn't really the focus of the Artificial Intelligence Act. Copyright and AI training is covered in the EU Copyright Directive 2019/790, and is very similar to the Japanese law. The AI Act basically just reiterates that AI models have to disclose exactly what they were trained on, something already implied by CD 2019/790.
