Github user wido commented on the issue: https://github.com/apache/cloudstack/pull/1633 Do we seriously want to write code that still works on CentOS 6 or systems without Python 2.7? Looking at the Python website: https://docs.python.org/2/library/optparse.html <pre>Deprecated since version 2.7: The optparse module is deprecated and will not be developed further; development will continue with the argparse module.</pre> I wouldn't call this a blocker at all. CentOS 6 is pre-historic and we can't go back to using a old module like OptParse. Sorry, -1 for me on this one.
