Except that previously this wasn't racy behavior in practice. I have automation tooling that has executed tens of thousands of reboot and shutdown commands over SSH in this way with perfect consistency over the last two years. The moment the switchover to systemd happened in Vivid, this tooling broken.
I get that my assumptions weren't robust and that I have to change my tools to accommodate systemd (which I already did). But communicating this change is courteous and helpful, very Ubuntu if you will. And this isn't something that needs to be prominent. It just effects people working with servers, VMs, etc, not everyday desktop users. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1429938 Title: reboot does not return under systemd Status in systemd package in Ubuntu: Invalid Bug description: If you send a shutdown or reboot command over SSH to a Trusty or Utopic host, the command will consistently finish successfully prior to the SSH connection being closed, meaning your SSH client will exit with a return-code of zero: For example: $ ssh root@myhost shutdown -h now $ echo $? 0 Or $ ssh root@myhost reboot $ echo $? 0 However, on Vivid now that the switch-over to systemd has happened, running the same consistently results in the abrupt closure of the SSH connection prior to the command finishing, meaning your SSH client will exit with a return-code of 255: $ ssh root@my_vivid_host shutdown -h now Connection to localhost closed by remote host. $ echo $? 255 Although in retrospect is was a bit naive for me to rely on this (actually quite fragile) behavior, it had at least been consistent in Ubuntu for some time (back to at least Raring from my personal experience, but likely back even farther). This isn't technically a systemd bug, but I still think it's something worth mentioning in the release notes as I bet I'm not the only person who built some "clever" hacks around the previous behavior :P To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1429938/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
