I assume the promised ability to do an archive and install ala
MacOS X hasn't made it into FC5. Is that correct? Linux is never
going to make significant headway on the desktop until we get
rid of the need to wipe and reinstall every time a system release
occurs.

I upgraded from FC3 to FC4 both by yum and CD (upgrade) on several
machines. Both went smooth. Here is the link I used to upgrade with yum:

The link has good points for upgrading via yum. The problems I
encountered with FC4 to FC5 test related to hotplug. This program was
removed in lui of other ways to mount USB devices. What you need to do
is run rpm -e hotplug and note the packages which depend upon hotplug,
sane-backends is one of the packages. So update sane-backends and any
other hotplug programs first. After upgrading the programs which depend
upon hotplug, update initscripts which will pull in a lot of packages
and also remove hotplug and setup things for the new usb changes between
FC4 and FC5.
Install the fedora-release package for the FC5 release. Update yum and
its dependecies, drop to runlevel 1, put selinux into permissive, start
networking. Next you can update the packages that do not relate to
SELInux. After the FC5 kernel is installed, you must reboot the computer
so that SELinux policy and %pre and %post scripts work properly.
What I did after updating, correcting ant noticed problems with the
system was to run 'fixfiles relabel to clear out temp and properly
relabel the SELInux content for proper operation.
Troubling areas for using yum to upgrade from FC4 release to FC5 release
is there are a lot of different factors like xorg-x11 going modular,
hotplug being discontinued and the like. It probably is not wise to
attempt this method unless the installer gives you problems like
exceptions or does not like some item on your system.
I don't suggest disabling SELinux altogether. It is setup to use
features within the FC5 kernel version which are not contained within
the FC4 kernel. You just need to ensure the kernel contains the needed
bits between version upgrades.
Use the installer if it works for you. I reported several problems
related to the installer and they were claimed t be fixed
post-last-test-for-FC5 install media. A yum update is possible but is a
bit of trouble to install using this method. There is also new features
available to add during the upgrade related to Xen. You can install
those features post-install but probably with lesser results than the
installer would give you. I would like to see a screen to display
options to include new items from release to release as xen is offered
as an add-in within the future releases. Upgrading would then not
short-change you by not offering the latest and greatest add-ons from
release to release.
