Yum upgrade/update question
 

To what extent would yum update/upgrade packages?

Currently running php 4.x and MySQL 4.x

I don't really want to upgrade those to later version, but will a yum upgrade do so? Even upgrade to version 5 without question?

I want to do an accross the board upgrade of my system as I ust installed FC2.

Certainly want to avoid unwated upgrades.

Thx

A plain "yum upgrade" will replace all packages on your system with the more recent ones from the repositories you use. However, you can ask yum to exclude some packages. i.e. "yum --exclude=mysql upgrade"

This can also be added to the yum.conf file.
