** Description changed: + The first half of the original bug report got fixed in bug 1578833, but + pollinate still runs to early. + + SRU INFORMATION + =============== + Impact: Causes service failures during boot when using NFS mounts, regression from bug 1578833 + Reproducer: + - sudo apt-get install -y nfs-common pollinate + - echo "1.2.3.4:/foo /mnt nfs defaults,nofail 0 0" | sudo tee -a /etc/fstab + (This will start network-online.target during early boot) + - sudo reboot + - Confirm that "sudo journalctl -b -p warning" shows a dependency loop, and most probably "systemctl status network-online.target" is not running. + - Upgrade to the proposed pollinate update, reboot. + - Confirm that there is no dependency loop any more and "systemctl status network-online.target" is active. + - Confirm that /etc/systemd/system/network.target.wants/pollinate.service does not exist any more. + + Regression potential: Low. This merely changes when pollinate.service + gets activated, and network.target is too early (nothing should actually + be started by network.target, this is mostly meant for shutdown). The + main thing that can go wrong is that the upgrade still leaves the old + /etc/systemd/system/network.target.wants/pollinate.service symlink + behind (the maintainer scripts have to clean that up). + + + Original bug report: + pollinate runs too early on some of the instances i launch. Basically nothing guarantees that it will have network access when it attempts to run. failure looks something like: - $ lxc launch xenial x1 + $ lxc launch xenial x1 $ sleep 4 $ lxc exec x1 systemctl status pollinate ● pollinate.service - Seed the pseudo random number generator on first boot - Loaded: loaded (/lib/systemd/system/pollinate.service; enabled; vendor preset: enabled) - Active: inactive (dead) since Thu 2016-04-28 17:16:03 UTC; 1min 17s ago - Process: 86 ExecStart=/usr/bin/pollinate (code=exited, status=0/SUCCESS) - Main PID: 86 (code=exited, status=0/SUCCESS) + Loaded: loaded (/lib/systemd/system/pollinate.service; enabled; vendor preset: enabled) + Active: inactive (dead) since Thu 2016-04-28 17:16:03 UTC; 1min 17s ago + Process: 86 ExecStart=/usr/bin/pollinate (code=exited, status=0/SUCCESS) + Main PID: 86 (code=exited, status=0/SUCCESS) Apr 28 17:16:03 ubuntu systemd[1]: Starting Seed the pseudo random number generator on first boot...
