That created a dependency loop between cloud-init.target and multi-user.target and cloud-final.target. Most of the time systemd would break that loop by dropping cloud-init.target. But sometimes, it would break the loop by dropping cloud-final.target, which would mean that user scripts do not run and generally cloud-init doesn't finish. [Test Case] ## Failure in a xenial image can only be reproduced by ## patching an image up to the previous xenial-proposed upload ## (0.7.7-31-g65ace7b-0ubuntu1~16.04.1), then cleaning it ## and then restarting. We will focus on verifying there is not ## a problem. ## Launch an instance and patch it up to xenial-proposed $ release=xenial $ name=x1 $ lxc launch ubuntu-daily:$release $name # wait for it to boot $ while ! lxc exec $name -- [ -e /run/cloud-init/result.json ]; do sleep 1; done ## Now update container, clean and reboot to show first boot $ lxc exec $name -- sh -c ' p=/etc/apt/sources.list.d/proposed.list echo deb http://archive.ubuntu.com/ubuntu xenial-proposed main > "$p" && apt-get update -q && apt-get -qy install cloud-init' $ lxc exec $name -- sh -c ' cd /var/lib/cloud && for d in *; do [ "$d" = "seed" ] || rm -Rf "$d"; done rm -Rf /var/log/cloud-init*' ## This is like first boot now. $ lxc exec $name reboot $ while ! lxc exec $name -- [ -e /run/cloud-init/result.json ]; do sleep 1; done ## The services should show active $ lxc exec $name -- journalctl | grep Break || echo Good, no breaks $ lxc exec $name -- systemctl --no-pager status cloud-final.service $ lxc exec $name -- systemctl --no-pager status cloud-init.target [Regression Potential] Playing with boot order can cause problems. Regression would be around some targets not running. On a booted system this would show itself inx journalctl | grep -i Break or journalctl | grep -i ordering ==== End SRU Template ==== With current yakkety cloud images (at least in Scalingstack), I often run into this dependency cycle at boot: Sep 15 09:28:51 ubuntu systemd[1]: cloud-init.target: Found ordering cycle on cloud-init.target/start Sep 15 09:28:51 ubuntu systemd[1]: cloud-init.target: Found dependency on cloud-final.service/start Sep 15 09:28:51 ubuntu systemd[1]: cloud-init.target: Found dependency on multi-user.target/start Sep 15 09:28:51 ubuntu systemd[1]: cloud-init.target: Found dependency on cloud-init.target/start Sep 15 09:28:51 ubuntu systemd[1]: cloud-init.target: Breaking ordering cycle by deleting job cloud-final.service/start Sep 15 09:28:51 ubuntu systemd[1]: cloud-final.service: Job cloud-final.service/start deleted to break ordering cycle starting with cloud-init.target/start ● cloud-final.service - Execute cloud user/final scripts Loaded: loaded (/lib/systemd/system/cloud-final.service; enabled; vendor preset: enabled) Active: inactive (dead) Thus /var/lib/cloud/instance/boot-finished never gets written and thus waiting for an instance to init just times out.
