Upgrading Mango on Linux

I've finally gotten around to upgrading Mango to 1.2.2 for this blog but it wasn't without adventure. Version 1.1 introduced an automated updater. The update process to 1.1 went without incident. But when I tried updating to 1.2.2, I got some file permissions errors. I'm running CFMX 7 on Linux. I've run into some file permissions error like this before so I had thought I solved them by creating a group that Apache and the files in the websites. But I still had the errors after resetting the permissions on the root for the blog. Then I discovered that CFMX wasn't running under any user name but as "nobody". I cahnged that to a real user (created just for this) and then I was getting some errors when starting CFMX. I reset the ownership on all the CFMX files /opt/coldfusionmx, restarted and all was fine.
