I downloaded the iso images for FC4 and burned CDs. I then upgraded my FC3 system with the CDs. After the upgrade, two things quit working. When the screensaver tried to kick in, I would get an error message on the screen. Further investigation revealed the various screen savers were missing. Once I installed the xscreensaver packages, I was back in business. I saw on bugzilla that the xscreensaver was broken in to three packages. Also, my cups-lpd functionality went away. I had to manually install cups-lpd to get this working. I did not see this on bugzilla so I reported it. I reviewed the release notes and didn't see anything about either of these. Is there anywhere I could have looked to avoid these issues in the first place. It also makes me wonder if there could be something else lurking out there that I haven't stumbled on yet. ==
