| wjb | I have read that `service reload` sends SIGHUP, causing the daemon to reread its configuration. If the configuration has changed, will the daemon die and be replaced by another process that has read the new configuration? | 14:01 |

| hikiko | hi | 14:45 |
| hikiko | I am trying to find out where the log_daemon_msg messages go to get the output of a startup script I have in /etc/init.d (the lightdm script) but I cant find it.. any ideas? (thanks) | 14:46 |
| jodh | wjb: 'reload' simply sends the main job process the appropriate signal. Use 'stop $job && start $job' to make the job restart with latest *upstart* configuration. | 15:20 |
| jodh | hikiko: /var/log/boot.log | 15:22 |
| hikiko | jodh, it's not there and ideally I'd like to see the messages each time I restart lightdm | 15:24 |
| hikiko | not only at boot time | 15:24 |
| wjb | jodh: Thanks. Another question if you a moment: the upstart script I'm working on has a script stanza that contains "exec sudo -u www-data my-server-script". So I see that process running as root, and I also see a process running my-server-script as www-data. Which of these does upstart see as the main job, and therefore send signals to? | 15:25 |
| jodh | hikiko: hold on - on an ubuntu system, lightdm is an upstart job, not a SysV one. Any output from lightdm goes to /var/log/upstart/lightdm.log. | 15:25 |
| wjb | jodh: I want the signal to go to the www-data process, not the sudo. But I'm not sure that is happening. | 15:25 |
| hikiko | jodh, ** (lightdm:2044): WARNING **: Session pid=2164: Error writing to session: Broken pipe | 15:26 |
| hikiko | that's the only type of messages I see there | 15:26 |
| hikiko | and also I added an echo "my message" >> /tmp/foo | 15:26 |
| hikiko | and there's no /tmp/foo created | 15:26 |
| jodh | wjb: if you have upstart >= 1.4 ("initctl version") use the 'setuid' and 'setgid' stanzas rather than sudo. See http://upstart.ubuntu.com/cookbook/#run-a-job-as-a-different-user, http://upstart.ubuntu.com/cookbook/#setuid, http://upstart.ubuntu.com/cookbook/#setgid | 15:27 |
| jodh | wjb: as for which pid it tracks, it will track the first by default. See http://upstart.ubuntu.com/cookbook/#expect (worth reading atleast twice! :-) | 15:27 |
| wjb | jodh: Thanks! I just read that for the first time a few minutes ago and am still digesting it. :) | 15:28 |
