In fact, I believe it was mostly for the benefit of
sitepackages=True that we started adding it. If my recollection is
correct, faced with a requirement of foo>=3 and a system install of
foo==2 pip under tox would refuse to upgrade to meet the stated
requirement and would instead just use the (non-conforming) version
from the system (system-wide installs of old Jinja on CentOS 6 seems
like where nova ran into this).
