[PKG-Openstack-devel] Bug#859194: neutron: please make the build reproducible

Source: neutron
Version: 2:9.1.1-1
Severity: wishlist

Hi,

Whilst working on the Reproducible Builds effort [0], we noticed
that neutron could not be built reproducibly as it includes the
number of CPUs in the metadata_agent.ini config file.

Patch attached.
