Yes. Its -always- about deployments. Case in point: transitioning a Python version in a slow fashion in production means: - buildbot (or $whatever CI) needs to run *two* version (old python version and new one) - we have to do everything related to that twice for a period If an OS upgrade is bundled into that, we have a multi-hour process for moving each component over, so we have no choice but to go slow. If we had a simple export PYTHON= and rebuild change, then a single deployment can upgrade us on all machines at once. Bada-boom, bada-bing. We do need to be reasonably sure before we kick the actual transition off, that its going to work, but instead of a Big Deal, its relatively no-brainer. -Rob _______________________________________________ Mailing list: https://launchpad.net/~launchpad-dev Post to : launchpad-dev@lists.launchpad.net Unsubscribe : https://launchpad.net/~launchpad-dev More help : https://help.launchpad.net/ListHelp
