Use mrepo to create your own repository

Dag Wieers created a great tool to setup a Yum/Apt mirror from difference sources. http://dag.wieers.com/rpm/packages/mrepo/

Why create a local repository while everything is online? There are may reasons. For me, most important two reasons are:

1. Build freezy version, keep all your system running same version of program

2. Less bandwidth consummation for my ADSL, and faster local installation
