One of the major features using a distro over upstream gives is integration. rhel6 behaves differently then ubuntu 13.10. Sometimes it takes a while to fix upstream for a given distro, and even then it may not even be accepted because "the distro's too old, go away". Packages allow a distro to make sure all the pieces can work together properly. And quickly patch things when needed. Its kind of a fork but not quite the same thing. The distro integrates not just OpenStack, but all its dependencies and their dependencies all the way up. For example there can be subtle issues if neutron, open vswitch and the kernel are out of sync. It is the integration that folks like about distro's. "I can trust that since it came from X, all the pieces should work together, or I know who to call".
The only way I can think of to get the same stability out of just source is for Triple-O to provide a whole source distro and test it, itself. More work then it probably wants to do. Or pick just one distro and support source only on that. Though if you pick the wrong distro, then you get into trust issues and religious wars. :/ Kevin ________________________________________ From: Clint Byrum [[email protected]] Sent: Tuesday, January 07, 2014 3:04 PM To: openstack-dev Subject: Re: [openstack-dev] [TripleO] Installing from packages in tripleo-image-elements Excerpts from Chris Jones's message of 2014-01-07 14:43:31 -0800: > Hi > > > On 7 Jan 2014, at 22:18, Clint Byrum <[email protected]> wrote: > > Packages do the opposite, > > and encourage entropy by promising to try and update software > > Building with packages doesn't require updating running systems with packages > and more than building with git requires updating running systems with git > pull. > One can simply build (and test!) a new image with updated packages and > rebuild/takeover nodes. > Indeed, however one can _more_ simply build an image without package tooling... and they will be more similar across multiple platforms. My question still stands, what are the real advantages? So far the only one that matters to me is "makes it easier for people to think about using it." _______________________________________________ OpenStack-dev mailing list [email protected] http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev _______________________________________________ OpenStack-dev mailing list [email protected] http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
