Not quite sure we support running it on Windows nodes, either way this looks a bit more future proof:

This only checks whether the path is rooted, and therefore would return true for /abc/.../bin. We must call filepath.Clean(path) to ensure that becomes /bin before we do all the checks we are doing here.

This will probably not work very well if executed in Windows. Perhaps string(filepath.Separator) could be used instead. Either way, it would be good to have unit tests showing all the inputs and outputs we have considered.
Suggested change
