------- Comment From thierry.fa...@fr.ibm.com 2014-11-19 08:29 EDT------- Looking at the man page, upstart is related to init process. When a start cmd is issued there is a connection with init process to have the command being handled by init daemon. So I don't think it is possible to manually start a process and then have init handling it. Your request doesn't seem valuable for me unless you get another poinr of vue.
The only solution I see is that you put in your manual start script a check to issue a start command if not already started by it. -- 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.
