Comment 2 for bug 1316326

Hi Dean,

Thank you for the comment.
Maybe my description is not clear, let me explain a little bit.
First of all, this is an exception case, as my understanding, if someone runs into the exception, he or she should be able to run again in a correct way without any side effect.
In this bug report, when a user runs devstack without proper permission, the devstack failed. Then we grant proper permissions and run devstack again, it still fails because of the side effect of the first running, which should not happen.

Basically, the bug is about eliminating the side effect of running while lacking proper permissions.
