Suggestions for stuff to put in this wiki

• Checklist for apache, squid, DB, to avoid snafus like the whole site going down because logrotate wasn't set up properly on a single squid.
• Explanations of stuff which you look after so that others can fix it more easily if it breaks and you're not around.
• Some faqs about common unix tools, useful scripts.
