My report appears to be invalid. My Plymouth hadn't been updated to take the /run transition into account, even if initramfs had been. At least that's the conclusion I draw. After reverting to a stable baseline, updating Plymouth, then updating base-files and initscripts, everything worked, even after a cold boot.
My apologies. Even if the updates really did make their appearance at the same time, it became increasingly difficult to keep track of which package triggered any given consequence. ** Changed in: sysvinit (Ubuntu) Status: New => Invalid ** Converted to question: https://answers.launchpad.net/ubuntu/+source/sysvinit/+question/165176 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/811385 Title: reboot hangs at Plymouth logo after upgrading base-files and initscripts To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sysvinit/+bug/811385/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
