Feature request: add Fedora image

[kolyshkin]

Description

It would be nice to have more images, such as Fedora. I am asking for Fedora specifically because

1. Fedora has unique features not (yet?) available elsewhere. From my recent experience, these are:
   1.1. cgroupv2 enabled by default. Theoretically, this can be done in Ubuntu as well. Practically, it requires changing a kernel boot parameter and a reboot, so it's not available with GH actions.
   1.2. A recent kernel with new syscalls (such as openat2).

I am one of runc maintainers. Runc is a building block for all modern containers, including Docker and K8s. It is currently not possible to test cgroupv2 or openat2 support in runc using GH actions. I am pretty sure many other low-level software components hit the same limitation.

2. Fedora has package management (rpm/yum) which differs a lot from Ubuntu (apt/dpkg). This is essential for people who develop on/for RPM-based distros.

Some other requests about having Fedora list other reasons, so I won't repeat them here.

• Fedora/CentOS #1443
• Linux distribution available as virtual environments for GitHub Actions ( or rather lack there of ) #45
• Fedora runner runner#898

Finally, don't get me wrong, I am not trying to pry or annoy the github team. In #1443 (comment) @maxim-lobanov says:

Since we see popularity of this request, we will keep it on mind and will be able to revisit this decision in future.

So, maybe the time to revisit is now? 👍

Question, Bug, or Feature?:

I would also add SELinux as a unigue feature.

Hello @kolyshkin , thank you for raising the issue and providing additional context about benefits from adding Fedora image.
Unfortunately, we don't have plans to add additional images yet. Mostly, it is about maintenance concerns for having more images.

Please consider using docker images or self-hosted agent for now.

Mostly, it is about maintenance concerns for having more images.

Perhaps you can roll it out as "unofficial" or "unsupported" and see if the Fedora community is big / strong enough to help ease the maintenance burden.

Please consider using docker images

I would love to, but features I described above (cgroupv2, openat2) and also selinux require a specific (== recent) kernel booted, so it won't work from inside a docker container.

👍 We would like to do some Cilium testing in GH actions. For that we need to run on cgroupv2 hosts.
