CLI fails to detect OS version on Arch Linux

[botirkhaltaev]

Summary

The CodSpeed CLI fails before running any local benchmark command on Arch Linux because OS version detection fails.

Environment

• CodSpeed CLI: codspeed-runner 4.18.1
• OS: Arch Linux rolling
• Kernel: Linux 7.0.3-arch1-2 x86_64
• /etc/os-release contains ID=arch and BUILD_ID=rolling, but no VERSION_ID.

Commands tried

• codspeed status
• codspeed setup
• codspeed exec -m walltime --repository botirkhaltaev/runic --enable-profiler --perf-unwinding-mode dwarf --warmup-time 0s --min-rounds 5 --max-rounds 5 --name runic-single-size-churn-64 -- target/release/rss --case runic single_size_churn_64 200000

Actual behavior

All commands fail or report:

Failed to get OS version

codspeed exec exits before running the benchmark command.

Expected behavior

Either:

• support Arch Linux by accepting rolling distributions without VERSION_ID, or
• return a clear unsupported-OS message that explains which OS/version fields are required.

Notes

The CLI is authenticated successfully. The failure happens before benchmark execution, so it blocks local profiling entirely on this host.
