This article is specific to CentOS, however the packages required for yum here are the same on other flavors
The below scripts installs all packages upon which yum depends for a 386 distro (Need separate 64 bit instructions)
Please note - that the version numbers of the packages WILL change as later releases come out, it is up to you to ensure that the packages used are the latest.
