| twb | I'm not sure if this is an ubuntu or an upstart question. | 06:03 |
|---|---|---|
| twb | I have a 12.04 chroot environment that I am installing packages into, as part of building a live image. When I install a daemon package (e.g. cron), it tries to start itself by talking to upstart. This fails (because it's chrooted). | 06:03 |
| twb | In sysvinit I would simply write a policy-rc.d that said "exit 101", which tells invoke-rc.d not to ever start such daemons. | 06:03 |
| twb | How can I get the same effect for upstartized daemons? | 06:04 |
| twb | In the past, it seems the least-worst approach was to diver initctl and put /bin/true in its place during the build. | 06:07 |
| twb | http://bugs.debian.org/571054 | 06:07 |
| twb | OK, never mind. I just tried writing a policy-rc.d and it seems that approach works now. Yay! | 06:10 |
| tcr | Is seems like "start on" does not actually specify a prerequisite for a job to be started, but a pattern of events that if fullfilled will make the job be started automatically. Is that correct? | 13:57 |
| jodh | tcr: yes - see http://upstart.ubuntu.com/cookbook/#start-on and http://upstart.ubuntu.com/cookbook/#upstart-s-design-why-it-is-revolutionary | 17:30 |
| tcr | I have a job definition which contains "start on", "stop on" and a "pre-start script" - that's it. I'd have thought that creates a forever-running job, but it seems not to (status $job reports "Unknown job") | 19:26 |
| tcr | I want to create a job that perform some action, and if the action was successful, remains in the started state (so an attempt to start it again will be a NOP) | 19:27 |
| JanC | unknown job means exactly that: there is no job with that name | 19:37 |
| JanC | so either your job definition contains syntax errors, or you misspelled its name... | 19:37 |
| tcr | other jobs were started that depend on it. Is a .conf file checked for syntax errors before or while it is being processed? | 20:25 |
| xnox | tcr: .conf jobs are loaded when upstart starts and are not reloaded. | 20:28 |
| tcr | sorry how does that answer the question? :) | 20:29 |
| xnox | sorry, as far as I know syntax is checked on loading, but I'm not sure with respect to buggy shell snippets and what not | 20:29 |
| SpamapS | tcr: if you have Ubuntu 11.04 or later you can use init-checkconf /ec/init/foo.conf | 23:00 |
| SpamapS | xnox: upstart jobs are reloaded if they change, and the filesystem supports inotify | 23:00 |
| xnox | SpamapS: ok. I had wrong impression. still learning upstart. | 23:02 |
