So we definitely want to work out the box on Alpine, so this issue is now tracking that.

We currently require glibc and that's probably the main difficulty we’ll have here.

I'm surprised the error is not found however, was expecting a dynamic linking lookup failure.

I added a test for alpine, but mysteriously the GitHub Action doesn't even work: https://github.com/teaxyz/setup/actions/runs/3759314481/jobs/6388731172#step:4:7

To me it looks like the action works, because line "determining latest tea version…" definitely comes from action.

The problems is /github/home/opt/tea.xyz/v0.17.2/bin/tea: not found. Maybe there is no /github/home/opt at this point. I don't know.
