I would like to save init log-prority debug options.

What is the whole process from startup event?

However, the init log-priority option to reboot and reset to the message.

What should I do?

If there is no way to modify the upstart source code what should I do?

'sudo initctl log-priority debug' will set the most verbose log level. You should be able to view the logs at /var/log/syslog, or if it's a custom script the logs might be at /var/log/upstart/[script-name]

If you want to view output during the boot process (instead of just post-boot) then you'll need to pass --verbose or --debug to the kernel command-line, as detailed in the Upstart Cookbook: – thinkmassive Feb 11 '14 at 1:50
