------- Comment From vcd...@us.ibm.com 2014-10-09 17:08 EDT------- (In reply to comment #7) > do you need to have scripts being fixed for you? Yes, need to fix/enhance Upstart for me and other customers who accidentally type in and run a job at command line, or start the job from crontab, because once that was done (i.e. the job was started from outside of the Upstart), Upstart will be unable to stop/restart the job.
> are daemons missing permissions to execute properly and retrieve infos ? No, the Upstart daemon has all the permission to do the expected things (stop/restart a job). It simply just can not function as what I expect. Perhaps some people just think not Upstart's business to handle (stop/restart) the process which it did not ever run? I believe the problem was clearly described at the defect opening. -- 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/1337407 Title: Upstart can NOT handle service/job started by others Status in “upstart” package in Ubuntu: New Bug description: -- Problem Description -- Upstart can not see a service/job/process that has been started and running by someone else. Old style init.d/systemd fully/partially handle start/stop correctly (on other Linux systems without Upstart), no matter who started the process. Our PMLinux collecting agent "daemon_PMLnx" was designed to start/run by root with any means, such as crontab, inittab, service, or even command line at a terminal. The program itself will quit immediately at the beginning if finds the process already running. Generally, we prefer to organize PMLinux as a service, plus create a start hook in the crontab to run "daemon_PMLnx" at 3am every day, in order to guarantee a restart won't be forgot if someone ever stopped the job.
