It seems I misread the logs when I said I was seeing the jobs being triggered as if the 'startup' event has been emitted. I cannot reproduce this behavior on a stock trusty VM with a normal root. There is no evidence that 'startup' is being emitted again, and no mountall process being spawned.

The point of this is that if restart is set, --restart is already present in args_copy so shouldn't be added (again). So, since I couldn't reproduce this issue on a stock trusty VM, I'm trying now with a liveCD booted under VM since that's how it's reported to be reproducible - so I can see what the state of upstart is before re-exec. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to upstart in Ubuntu. https://bugs.launchpad.net/bugs/1464442 Title: installing or upgrading libc6 in Trusty removes all content from /tmp directory Status in linux package in Ubuntu: Invalid Status in upstart package in Ubuntu: Triaged Bug description: We are seeing an issue with installation of dkms package during a curtin installation which ends up with /tmp directory being wiped clean. This is very bad for curtin as it saves critical installation files in /tmp. It turns out that it's the of upgrading libc6, which is triggered as a result of installing dependencies, that removes content of /tmp. For example, installation of gcc results in the same result since it ends up with libc6 being upgraded. The only way that this won't be recreated is if the latest libc6 is already installed. This problem does not exist in precise. It can also be recreated by installing the .deb file for any version in trusty including 2.17. ======================================================================== ubuntu@host:~$ ls /tmp tmpHHbRkP ubuntu@sirrush:~$ sudo apt-get install libc6 sudo: unable to resolve host sirrush Reading package lists...
