Questions[upstart](ubuntu)

I am using upstart for services on my servers. Writing a conf file and placing it in /etc/init is easy enough, but that doesn't seem to completely install. For one, the service --status-all doesn't list my new service. I checked and if I make a link in /etc/init.d to /lib/init/ubstart-job it'll show up in the status. But doing this manually makes me think I'm not doing it right, and there may well be other configuration steps which aren't being done.

What is the correct way to install an upstart service such that it is properly registered in all tools dealing with services?

For some reason I'm getting an error during apport upgrades, the cause of which is

% sudo service apport start
start: Job failed to start

Under sysvinit, I could debug this kind of problem by running eg

sudo sh -x /etc/init.d/whatever start

but that doesn't seem to map over to Upstart. What should I try next?

It turns out there is a workaround that will let the install proceed. But I'm still interested in the general question of how one would trace the script.

I read about how to enable and disable services in Ubuntu and it seems that there are different possibilities to manage them.

The first method I found is update-rc.d to add new services to startup, which aims on the /etc/init.d folder and its contents.

The other one I found is to edit .conf files in the /etc/init folder.

What's the recommended way to enable / disable / add services and why?

Could you please give a short bulletproof step by step example on how to add a service in Ubuntu and enable and disable it?

I've been managing server installations both on and off Ubuntu flavor for some time - I've become quite adjusted to /etc/init.d/ for restarting servcies. Now I get this message:

root@tatooine:~# /etc/init.d/mysql status
Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service mysql status

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the status(8) utility, e.g. status mysql
mysql start/running, process 14048

This seems to have been brought about in the latest LTS of Ubuntu - why? What's so bad about /etc/init.d/ and what/is there a difference between service and /etc/init.d/?

Is there a command to list services that run on startup? I imagine it would involve parsing /etc/init.d/, and the various /etc/rc.* directories.
