On Yum support for Unbreakable Linux Network (ULN)

Recently, the ULN team added Yum support. This means that anyone running Oracle Linux 5 registered with ULN can now use yum instead of up2date to download and install packages. If you have already run a full update since Oracle Linux 5.6 was released on January 20th 2010, you should already be able to use yum against ULN.

If you are running Oracle Linux 5 and want to enable ULN yum support without updating any other packages, install yum-rhn-plugin as follows. This assumes your system is already registered with ULN:

# up2date --install yum-rhn-plugin

With that installed, you can immediately being using yum. For example:

# yum repolist
Loaded plugins: rhnplugin, security
repo id repo name status
ol5_x86_64_latest Oracle Linux 5 Latest (x86_64) enabled: 4,647
repolist: 4,647
# yum info oracle-validated
Loaded plugins: rhnplugin, security
