[Bug 1124384] Re: reload-configuration can confuse upstart

[Scott Moser]

** Description changed:

- Example from failure: https://jenkins.qa.ubuntu.com/job/raring-server-
- ec2/ARCH=amd64,REGION=eu-west-1,STORAGE=ebs,TEST=multi-part-ud,label
- =ubuntu-server-ec2-testing/17/console
+ Under bug 1080841 we made cloud-init invoke 'initctl reload-
+ configuration' after it wrote a upstart job.  This was necessary because
+ inotify is not supported on all filesystems (overlayfs being the one of
+ most current interst).
  
- Cloud-init is parsing YAML incorrectly
- runcmd:
- ...  - [ sh, -c, "echo ============= $(date) ': hello world!' ============= " ]
- ...  - [ sh, -c, 'echo "$(date)" > /root/runcmd.date.txt' ]
- ...  - [ wget, "http://slashdot.org", -O, /tmp/index.html ]
- ...  - touch /tmp/done
+ This seems to be causing upstart some pain, and resulting in cloud-final
+ (and 'rc') not being run.
  
- Fails, while changing "- touch /tmp/done" to " - [ touch /tmp/done ]"
- works.
+ Easy user-data to reproduce the problem is:
+ 
+ #cloud-config-archive
+ - content: |
+    #!/bin/sh
+    echo "==== $(date -R): user-script run ===" | tee /run/user-script.log
+ - content: |
+    #upstart-job
+    description "a test upstart job"
+    start on stopped rc RUNLEVEL=[2345]
+    console output
+    task
+    script
+    echo "==== $(date -R): upstart job run ===" | tee /run/upstart-job.log
+    end script
+ 
+ You should (and do on quantal) end up with 2 files written to /run.
+ 
+ I've verified that the same behavior is true on quantal.  If you change
+ cloud-init to notify upstart about a job immediately after it writes it,
+ then quantal's upstart gets confused also.
+ 
+ Related bugs:
+  * bug 1080841: should reload configuration if an upstart job is added 
+  * bug 1103881: cloud-final is never executed if upstart is upgraded during initialization of the image
