[ale] Update RHEL subscription?

[James Sumners]

I have a new subscription number to replace an expired one. I really
don't want to have to login to all my systems and run `rhn_update`. Is
there an easier way to update the subscription number on a system such
that a `yum update` will be successful?

pathological personalities. It is not that power corrupts but that it
is magnetic to the corruptible. Such people have a tendency to become
drunk on violence, a condition to which they are quickly addicted."
