Upgrade a fresh CentOS 4.3 slice to CentOS 5.0

Starting with a freshly built CentOS 4.3 slice, login as root

Create temporary directory to hold packages:

#mkdir /tmp/Upgrades
#cd /tmp/Upgrades

Erase centos-yumconf (removes CentOS 4 repos)


#rpm -e --nodeps centos-yumconf

Import CentOS 5 GPG key:

#rpm --import http://mirrors.kernel.org/centos/RPM-GPG-KEY-CentOS-5

Download and install the centos-release-5 packages (adds CentOS 5 repos), then remove packages:
