Farewell RH 9...

Ungrade from Red Hat 9 to CentOS 4

This weekend I will be parting with my beloved Red Hat 9 to embrace CentOS 4. I've been using the Prodigy service to patch RH 9 since 05/04, but the availability of that support offering is now in doubt.

CentOS is a RHEL clone, and with YUM, I'll be able to upgrade RH 9.

The Yum upgrade (from CentOS Forums)..........

HOWTO: yum upgrade to CentOS 4.0

A method of upgrading from RH/Fedora/whatever to CentOS 4.0 with yum:

Substitute your choice of mirror sites

(install GPG key)
rpm --import http://www.gtlib.gatech.edu/pub/centos/4.0/os/i386/RPM-GPG-KEY-CentOS-4

(need these 3 files)
wget http://www.gtlib.gatech.edu/pub/centos/4.0/os/i386/CentOS/RPMS/centos-release-4-0.1.i386.rpm
wget http://www.gtlib.gatech.edu/pub/centos/4.0/os/i386/CentOS/RPMS/centos-yumconf-4-2.noarch.rpm
wget http://www.gtlib.gatech.edu/pub/centos/4.0/os/i386/CentOS/RPMS/yum-2.2.0-1.centos4.2.noarch.rpm

(install)
rpm -Uvh --force centos-release-4-0.1.i386.rpm centos-yumconf-4-2.noarch.rpm yum-2.2.0-1.centos4.2.noarch.rpm

(upgrade)
yum upgrade
After the list of packages is displayed, choose 'y' to download and install.

If a new kernel was downloaded, then you might need to modify the grub.conf to set the 'default' entry to the new kernel. Kernel entries in the grub.conf are numbered starting with 0, not 1.

Reboot. That's it! You're done!

As with RH 9, I'll have to add the NTFS driver, Linux-NTFS.
