Hi, I've noticed that the various oVirt projects are not using the DCO process correctly. While contributors are adding Signed-off-by's (Good), there's no Signed-off-by being added by maintainers (Bad). http://lwn.net/Articles/139918/ It may seem like a minor thing, but SOB is meant to provide a chain of custody and it's less effective if the certification isn't also done by maintainers. For VDSM, I see examples like: commit 53c6801658a8c5e05ceb518ffd9ebfefa805fda9 Author: Antoni S. Puimedon <asegurap@redhat.com> Date: Tue Dec 18 22:33:39 2012 +0100 Fix blockSD pep8. Change-Id: I2ed4ce2a5748a911f76da02f762e5bda9352b905 Signed-off-by: Antoni S. Puimedon <asegurap@redhat.com> Reviewed-on: http://gerrit.ovirt.org/10213 Reviewed-by: Dan Kenigsberg <danken@redhat.com> The last 'Reviewed-by' ought to be a 'Signed-off-by'. OTOH, ovirt-engine lacks any Reviewed-by tags. For example: Author: Sharad Mishra <snmishra@linux.vnet.ibm.com> Date: Wed Dec 26 11:10:32 2012 -0800 core: removed obsolete classes vm_template_image_map_id and vm_template_imag These clasees are not used anymore. Change-Id: I82f0861644f155f7b6c27ba5acb3a069b6f1a8f6 Signed-off-by: Sharad Mishra <snmishra@linux.vnet.ibm.com> I'm not sure if this is a limitation in gerrit. I know the question has come up regarding what OpenStack does. OpenStack doesn't use DCO. They have an explicit CLA that everyone must sign before participating[1]. DCO eliminates the need for such an agreement (when used properly). [1] http://wiki.openstack.org/CLA Regards, Anthony Liguori
