[wplug] Anyone out there really understand upstart...?

[Martin James Gehrke]

the most fundamental upstart script would be

# Ubuntu upstart file at /etc/init/yourservice.conf

pre-start script
    mkdir -p /var/log/yourcompany/
end script

post-stop script
    #do some cleanup
end script

respawn
respawn limit 15 5

start on runlevel [2345]
stop on runlevel [06]

script
su - youruser -c "NODE_ENV=test exec
/var/www/yourcompany/yourproject/yourservice.js 2>&1" >>
/var/log/yourcompany/yourservice.log
end script

You don't have to worry about the start and stop code in the upstart
init file, this would be handeled in the script or through upstart
itself.
