Running Instiki from launchd under Tiger

« Tamrac 5691 - Killer Little Digital Camera Bag | Main | Origins of the term 'Swamp Yankee' »

After getting tired of starting Instiki by hand all the time, I finally sat down and figured out how to write launchd configs this morning. Launchd is the new way to start daemons, cron jobs and inetd style services in OS X Tiger. You'll need to create an unpriviledged user for Instiki and give them read/write access to the storage directory. Without further ado, here is the config file.

Update: I received an email the other day with a fix for this launchd plist. Apparently, I had forgotten to include the program itself in ProgramArguments array, which exec treats as the argv array. Thanks go to Adam Ingram-Goble of Indiana University for pointing this out to me. Sneers to Apple for misnaming the key. Given this information, they should have called it CommandLine instead.
