This wiki started life as a way for me to document how I'd set up my own systems. It's not quite as comprehensive as intended, but it seems (from the referrer stats) that some people have found it useful.
I've set the wiki read-only (without a login; and disabled new account creation) but there's probably a blackhole email address for anyone who notices issues with what's on here.
