Upgrading Tao remotely

I successfully upgraded Tao1 -> Tao4 with yum and a lot of patience.
Here is my receipe for a desktop installation:

0. Make sure you have sufficient space left on your partition. I needed
    about 3 Gb to perform the upgrade.
1. Remove any kernel-module you may have installed (e.g. nvidia driver,
    alsa-driver, ndiswrapper, etc.).
2. Install manually yum-2.2 (testing in tao-1.0) and
    tao-yumconf (tao-4) with rpm.
3. Edit /etc/yum.repos.d/taolinux.repo and replace $releasever by "4".
4. Run "yum update". It takes several minutes...
5. Note all packages having a missing dependency problem. Remove them
    with "rpm -e <package>".
6. Repeat until the only error you get is:
    Error: udev conflicts with kernel < 0:2.6
7. Set the initdefault at 3 in /etc/inittab.
8. If present, remove rhgb option in /etc/grub.conf.
9. Reboot the system.
10. Retreive those rpm packages from tao-4 repository:
    device-mapper
    gd
    glibc
    glibc-common
    glibc-headers
    glibc-utils
    kernel
    libselinux
    lvm2
    mkinitrd
    module-init-tools
    nscd
11. Install them with "rpm -Uvh *.rpm". You may encounter some
    package dependency problems. Get all the required RPM
    packages until the last error is due to lvm2 conflicting
    with lvm. Sometimes, removing an optional package may help.
    I had to remove webalizer and glibc-devel.
12. From now on, you should not reboot the system until the upgrade
    is completed. Force the installation with "rpm -Uvh --force *.rpm".
13. Install the Tao-4 GPG key
    rpm --import http://dist.taolinux.org/tao-4/i386/dist/RPM-GPG-KEY-dlp
14. Perform the upgrade: "yum -y update"
15. Check for broken symlinks
    /boot/System.map
    /etc/alternatives
    /etc/X11/X
    /usr/bin
16. Recreate your initrd:
    rm /boot/initrd-2.6.9-5.0.3.EL.img
    mkinitrd /boot/initrd-2.6.9-5.0.3.EL.img 2.6.9-5.0.3.EL
17. Edit /etc/fstab and comment out any uneccessary mount point
    (e.g. external USB drive).
18. Reboot
19. Remove yum and tao-yumconf with rpm.
20. Reinstall yum and tao-yumconf with rpm from Tao 4 repository.
21. Reinstall packages removed at step #5 and #11.
22. Reconfigure X
    (e.g. /dev/psaux -> /dev/mouse0)
23. Test X with "/sbin/init 5". If successfull, edit /etc/inittab
    and set initdefault at 5.
24. Restore /etc/fstab.
