Comment 4 for bug 956876

I've never had to alter or change permissions before. Nova services has always ran as 'nova'.
This is on a fresh install too.
Certainly wouldn't expect a bug to be closed because I can add a number of entries to sudoers.

Incidentally my sudo config is:
nova.conf:
--root_helper=sudo nova-rootwrap

sudoers:
#includedir /etc/sudoers.d

/etc/sudoers.d/nova_sudoers
Defaults:nova !requiretty

nova ALL = (root) NOPASSWD: /usr/bin/nova-rootwrap

Feels to me specifically related to packaging, setting the /var/lib/nova to root:root perms.
