This is something I've never seen before, I just rebooted one of my ubuntu 10.04 nodes and noticed all the startup services started twice.

My lish logview looks like this:

Starting apache2
Starting apache2
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs

 * Starting NTP server ntpd        * Starting NTP server ntpd            [ OK ] 
Starting daemon monitor: monit.

I checked I don't have duplicate startup links, if I do an update-rc.d -f mysql remove then reboot mysql doesn't start at all, re-adding it still makes is start twice.

The only things in my logs are warnings about everything starting twice.

Has anyone seen this before or have a clue where to poke to find out whats causing it?

Have you played with /etc/init.d/rc ? Maybe the concurrency setting is messing it all up?

Nope not touched it, it's a new linode too only a few weeks old :/ thing is I'm not sure if it's always done this. If all else fails I can try making a new node but meh thats time consuming!

Found the problem, I had a duplicate copy of /etc/init/rc.conf so upstart was running /etc/init.d/rc twice.
