I did some digging into systemd-tmpfiles and its configuration. In the trusty case, with systemd *not* running as PID 1, the systemd-tmpfiles does not strictly need to create /run/nologin to shield state transitions. For that, I removed creation of the file from trusty's systemd-tmpfiles configuration. Packages for testing purposes are in ppa :thomas-voss/trusty.
@Paul: Would be great if you could give the package a round of testing, too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1660573 Title: "system is booting up" while trying to log in after installing snapd on ubuntu 14.04 To manage notifications about this bug go to: https://bugs.launchpad.net/snapd/+bug/1660573/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
