Open Stack

Guessing this is due to the new tox feature which randomizes python's
hash seed.

Excerpts from Mike Spreitzer's message of 2014-08-24 00:10:42 -0700:
> What is going on with this?  If I do a fresh clone of heat and run `tox 
> -epep8` then I get that complaint.  If I then run the recommended command 
> to fix it, and then `tox -epep8` again, I get the same complaint again --- 
> and with different differences exhibited!  The email below carries a 
> typescript showing this.
> 
> What I really need to know is what to do when committing a change that 
> really does require a change in the sample configuration file.  Of course 
> I tried running generate_sample.sh, but `tox -epep8` still complains. What 
> is the right procedure to get a correct sample committed?  BTW, I am doing 
> the following admittedly risky thing: I run DevStack, and make my changes 
> in /opt/stack/heat/.
