How do I get Ubuntu upstart to not hang on interactive start & stop?

I have created many upstart scripts that work fine during init, but often hang when I enter them at the console. If I CTRL+C out, all that happens is that the job changes state. The script is never run.

I’m running Ubuntu Lucid on a Xen virtual server with a Linux 2.6.39 kernel.

Below is merely a representative example of many scripts that behave this way:

description "apache2"

start on local-filesystems \
  and (net-device-up IFACE=lo) \
  and (runlevel [2345])
stop on runlevel [016]

respawn limit 10 5

expect daemon

  . /etc/apache2/envvars
  /usr/sbin/apache2ctl start
end script

Check out my question on askubuntu.com about the same thing:


In the example you posted, it would come down to directly executing the apache binary vs. executing the apache2ctl script. Upstart expects the process it starts to not die immediately, basically; which is exactly what apache2ctl does.

There's a working Apache upstart script on my askubuntu.com question.
