Just thought I"d update everyone on my travails with the FC4 to FC5
upgrade. Because the upgrade itself just would not complete the first
disc, I blew away the original install and decided to try to install FC5
fresh. FC5 installed just beautifully, it was blazingly fast and I
didn't encounter any problems at all. (WEll, other than my 3TB LVM
volume not being able to set a mount point from the install)
Turns out, my predecessor, in his infinite wisdom, liked to install
every single package from in Fedora on every server he used here. It
didn't occur to me until earlier today that it's possible that yum was
choking on the sheer amount of packages (and most likely packages that
were moved from the FC4 base to Extras in FC5. If I had cleaned out all
the packages I didn't need on that server, it's likely the upgrade would
have been just fine.
Thanks again for all the help on this.
