Old version of QEMU

[tw00]

It looks like QUS is pointing to a fork of QEMU which hasn't caught up with the main repo in 3 years:

https://github.com/dbhi/qus/blob/f79aa71b04f5b1bfc98769edbf9a7a10659708fe/register.sh#L117C86-L117C150

The usage of that script is unrelated to the version of QEMU (the binaries) that are registered. The versions of QEMU that are used can be seen in https://github.com/dbhi/qus/blob/main/cli/config.yml. So, it's currently 7.2. It's also not up-to-date, tho.

Been pretty busy lately and did not have any specific reason to pursue bumping QEMU. Is there any feature in versions newer than 7.2 which you need? Or is it just a matter of keeping software updated?

With regard to the registration script itself, register.sh is just a wrapper around qemu-binfmt-conf.sh. Is there any relevant feature/enhancement in https://github.com/qemu/qemu/blob/master/scripts/qemu-binfmt-conf.sh which is missing in https://github.com/umarcor/qemu/blob/series-qemu-binfmt-conf/scripts/qemu-binfmt-conf.sh?

QEMU 9 has a number of important optimizations and bugfixes. One use case that is relevant to me, and that is broken on older QEMUs, is using the GitHub Actions Runner on the s390x architecture:

# docker run --rm --privileged aptman/qus -s -- -p x86_64
cat ./qemu-binfmt-conf.sh | sh -s -- --path=/qus/bin -p x86_64 --suffix -static
Setting /qus/bin/qemu-x86_64-static as binfmt interpreter for x86_64

# DOTNET_EnableWriteXorExecute=0 RUNNER_ALLOW_RUNASROOT=1 ./config.sh --url <redacted> --token <redacted>
qemu: uncaught target signal 6 (Aborted) - core dumped

If I upgrade qus as follows (debian moved the real binaries to qemu-user, so it's a little bit involved):
