Title:
dhcp agent uses root_helper setting from dhcp_agent.ini and
quantum.conf
Status in OpenStack Quantum (virtual network service):
Fix Released
Bug description:
Generally, the dhcp agent uses the root_helper setting from the
[AGENT] section of /etc/quantum/quantum.conf. However, there are a
couple of places where it uses root_helper from the [DEFAULT] section
of /etc/quantum/dhcp_agent.ini. I discovered this problem after I
followed the latest openstack installation guide for ubuntu. I saw
messages like this in the dhcp_agent log file:
Command: ['sudo', 'ip', 'netns', 'exec',
'qdhcp-0ad970b3-4f9e-445c-8b87-018d74fd02f2', 'quantum-ns-metadata-proxy',
'--pid_file=/var/lib/q
uantum/external/pids/0ad970b3-4f9e-445c-8b87-018d74fd02f2.pid',
'--network_id=0ad970b3-4f9e-445c-8b87-018d74fd02f2', '--state_path=/var/li
b/quantum', '--metadata_port=80', '--debug', '--verbose',
'--log-file=quantum-ns-metadata-proxy0ad970b3-4f9e-445c-8b87-018d74fd02f2.log',
'--log-dir=/var/log/quantum']

I'm going to submit a patch in a moment.
