Instead of treating inputs.php like a flake, it treats it as a path and imports it. Currently we have a failing CI tests, because under some circumstances inputs.php is a path and not a flake. This is buggy behavior in our backward compat mechanism which I don't intend to fix anymore in favor of the upcoming v1 API changes.

Probably does not make much difference, maybe passing system attribute here instead of hard-coding x86_64-linux.
