I wrote a startup script that starts at startup for ubuntu 9.10 server edition and does the rsync of my directories that is specified in my path, I did the startup in the old fashion way linking my script from init.d and placing it on run level, which is working and so i am able to start it on startup but after a while the service of my script is not running. It crashes on the middle after 5 minutes when the system is up and the code inside the script is just a line of rsync which i am sure is not the problem and so i have to invoke the script again to start it services? what is wrong with this? Can anyone help??
Check your /var/log/ directory for log entries -- I don't know upstart nearly as well as I should, but I hope it would kill any /etc/init.d/rc* task that runs for five minutes. init scripts should use start-stop-daemon to start specific programs that run for a long time. (That way, those same programs can be gracefully shut down at reboot or shutdown time.) But the scripts themselves should run in under a second or so.
I'd suggest writing an actual upstart management script and placing it into /etc/init/ instead of fighting with an init script. I don't think upstart is going away :) so you might as well get used to it.
