I'll take this.

I've previously did some cursory investigation into GitHub runners + FreeBSD, but GitHub themselves don't qualify their self hosted runners in BSD.

I'll investigate CircleCI, but a fourth option would be to create a new buildkite config, instead of repairing the existing one

Hi, this runs a little bit slow but did the job for me,

https://github.com/msktutil/msktutil/blob/master/.github/workflows/msktutil-freebsd.yml

I mean this action here,
https://github.com/vmactions/freebsd-vm

@mjtrangoni Thanks for the pointer to https://github.com/vmactions/freebsd-vm

I'll play around with freebsd-vm and see how fast it is, before opening a PR to add VMs into GitHub Actions

If you haven't seen it (I didn't see it mentioned in search results of this repo), there's also Cirrus CI which has native support for FreeBSD runners and is free for open source projects. I use it on one of my FreeBSD projects and it's been fine over the years. I'm obviously unsure how it would perform with a way more popular project like this one.

Did anyone have a chance to test these options?

I think drone also supports a freebsd agent.

Apologies, I ended up in the job market, which ate my spare cycles for the last few months.

I still care about this, but I realised I'm still an occasional contributor, not a prometheus maintainer (yet, maybe in the future). So the only option I can test is the vmactions option in Github Actions

Yeah nobody gets paid for these things so we depend on someone to contribute (or pay) for these things unfortunately. So any work, even if its coming up with a concept and validate the ideaas, is much apprieciated!
