This document is to explain how to upgrade your machine from Fermi Linux 7.3.1 to 7.3.1a. Although these steps have been tested, it is possible that if you have done alot of customizing to your operating system, or if you have a bad internet connection, some part of this upgrade will fail. These failures are usually not fatal to your system, only annoying. 1 - Make sure you have enough disk space. /var/cache should have at least 200M of space. This is where all the rpm's are downloaded. 2 - type 'yum update' This is what is going to actually do the upgrade. This will take a while. After yum has figured out what needs to be upgraded, it is going to list all of that for you and then ask you if this is ok. Type 'y' and away it will go. 3 - clean up the old yum Because the newer yum-conf works on a more flexible naming system, you will probrubly have some old yum cache's. It will be nice to clean these up since they may have up to 200M of downloaded rpm's in them, and it would be good to clean that up. rm -rf /var/cache/yum/server rm -rf /var/cache/yum/updates rm -rf /var/cache/yum/workgroup rm -rf /var/cache/yum/addons 4 - (optional) put on Fermi Logo's Because of trademark issues, we are trying to clean up all references to the redhat logo. the Fermi Logo package does this. Issue the command yum install zz_fermi-logos (hit y when it asks, or run the command 'yum -y install zz_fermi-logos') 5 - reboot You will have just gotten a new kernel with the update. Your bootloader (lilo or grub) should have been updated correctly. You may check them if you wish (/etc/lilo.conf or /boot/grub/grub.conf). You need to reboot in order to use the new kernel.
