When changing the ATrpms' repos to point to FC3 he/she will have to
change at the same time the other repos to point to FC3, too.

Unfortunately anaconda is quite drastic in "upgrading" leaving broken
dependencies behind. So yum will fail, and apt will need an apt-get -f
What you can do (and what I have done in half a dozen systems, I was
too lazy to reinstall from scratch, and didn't need a backup), is
o change the repos to point to FC3
o apt-get update
o check the FC3 release notes on how to manually upgrade a system [*]
o Perform these steps with apt-get install ..., reboot etc.
You basically need to upgrade initscripts, udev, mkinitrd (in this
order), install an FC3 kernel and reboot.
o After having successfully booted into an FC3 kernel do your
- apt-get upgrade and then
- apt-get dist-upgrade
Make sure you won't be sad if this system goes nirvana and does need a
reinstall, e.g. backup your data.
BTW nothing beats a fresh reinstall ...
[*] From the release notes:
Systems upgraded to Fedora Core 3 using Anaconda will automatically be
reconfigured to use udev. However (although NOT recommended) it is
possible to perform a "live" upgrade to udev using the following
1. Ensure that you are running a 2.6 kernel
2. Ensure that /sys/ is mounted
3. Install the initscripts RPM supplied with Fedora Core 3
4. Install the new udev RPM supplied with Fedora Core 3
5. Execute /sbin/start_udev
6. Install the new mkinitrd RPM supplied with Fedora Core 3
7. Perform one of the following steps:
. Install the new kernel RPM supplied with Fedora Core 3
. Re-run mkinitrd for your existing kernel(s)
Improperly performing these steps can result in a system
that will not boot properly.
