[Rdo-list] Devstack - why it uninstalls python-virtualenv?

That was beaten to death in old thread
http://lists.openstack.org/pipermail/openstack-dev/2013-August/013039.html
Nice summary is in Ian's commit message https://review.openstack.org/39862
tl;dr Debian avoids the issue by configuring its python to pip install
to /usr/local/ while Fedora/EL python maintainers refuse to diverge
from upstream, that's IIRC - I can't find rhbz with their comments,
maybe Ian will remember?


Cheers,
