There's a big server move afoot at work; we're ditching our overcharging colo hosts for a new bunch who charge a lot less. We are, temporarily at least, leaving one server behind to pretend to be the others and display a “we've moved” message.

The server in question is old (running Red Hat 7.1) and used to hold the main www pages for all our games. After moving them off though, it still thought of itself as “www”, which caused some confusion when I had a few x-terms open to the various servers. So I decided to rename it to something else.

In later versions of Red Hat, you can do that through system-config-network. In older versions, there's redhat-system-config - but that didn't seem to be installed, so I kicked up apt-get to see if it was available. It was... but...

The following packages have unmet dependencies:
  redhat-config-network: Depends: gnome-core but it is not going to be installed

So why wouldn't gnome-core install?

The following packages have unmet dependencies:
  gnome-core: Depends: sawfish but it is not going to be installed

And sawfish?

The following packages have unmet dependencies:
  sawfish: Depends: libcapplet.so.0

And apt-cache search suggests libcapplet.so comes with control-center - “The GNOME control center”.

The following packages have unmet dependencies:
  control-center: Depends: xscreensaver but it is not going to be installed

Hmm... ok. And why not xscreensaver?

The following packages have unmet dependencies:
  xscreensaver: Depends: /usr/games/fortune

OK... so I can't install redhat-system-config because I need fortune?

I'll install that then...

# apt-get install fortune

Lucky you can change the hostname with the hostname command isn't it...
