Well, that was a complete failure. Anaconda barfed while still doing the initial boot, and it doesn't appear to be an error that other people have answered (based on what Google finds). It's quite possible that something doesn't like my DVD drive, so I'll see whether I can get hold of a CD installation instead. Harumph. The damn thing managed to verify the disk was valid media before, though. :-(
Still, at least it barfed before it started messying with the system.
