I'm using RHEL5 to test this, anaconda version should be <a href="http://11.1.2.87">11.1.2.87</a>. that's so strange, I do think anaconda should wait pre-script finish then perform next action. Maybe os.wait() not work properly this case? so anaconda think the pre-script has already done while the subprocess of pre-script is still running.

You are sure you haven't added a '&' by mistake, or something like that? Or, it might depend on the Anaconda version; we are using Fedora 8.
