Looks like /dev/log/ was removed by intentionally and this bug is invalid.
But I believe the commit 1188d88a73e75da5c143d0dfad34e10dad0daee0 with removed /dev/log should had had a DocImpact tag and the change should be documented anyway.
E.g. something like "/dev/log/ will not be used by Openstack services anymore due to portability reasons, please make sure syslog listens UDP:514 port in order to recieve logs from Openstack."
