Follow-up.
Although I finally bought a fiire server and media director, due to many hardware and software issues I'm not running them 24/7. So I boot them every few days when I have time to 'play' a little.
Moving on to the real gist of this post. I started the server up and it offered me an update, again, even though I already have update 5. Rebooted in the unlikely event that update 6 came out 4-days after update 5, and of course, nothing happened.
So there's something broken there. It should check if any update is installed, before throwing up a message offering the update.
