Well, installing Microsoft SharePoint SP2 is actually remarkably straightforward (compared to the first Service Pack, anyway).
As always with Sharepoint, its important to turn off the web front end (simply stop the www service in the services applet worked for me) first to avoid users accessing the site in the process, install the WSS3 SP2 first, cancel the configuration wizard, then finally install the MS Office Server 2007 SP2.
No particular problem with dying servers though, and it worked on a server with live data. Comparatively a triumph, but still more complex than it should be. It also takes a heck of a long time to do the upgrade, and thats on a single server farm, with very little live data. I shudder to think of the potential impact to update a large farm.
Its quickly apparent that SP2 really helps sort out some of the standards in advance of IE8s general release – firefox looks so much better.
