Description of problem:
When reviewing the 5.4.1 RHN Satellite Installation guide on internal staging environment I noticed we were missing mention of RHEL 6 as a supported option for installation. 

The process for installing has not changed, compared to RHEL 5. 

We need to update the Satellite document to mention this. 

Version-Release number of selected component (if applicable):

Red Hat Network Satellite 5.4.1
 Installation Guide 
  Edition 2
   Revision 2-1	Fri May 27 2011

How reproducible:
Always
  
Actual results:
Inclusion of RHEL 6 along side of any mention of RHEL 5 for installation. Also, we should not be mentioning old installation on RHEL 4 AS - which use to be a supported option. So this is 'add RHEL 6' and remove any old 'RHEL 4' lingering in docs.

Expected results:

1) 
FROM:
Log into the RHN website (rhn.redhat.com) and download the distribution ISOs for Red Hat Enterprise Linux AS 4 or Red Hat Enterprise Linux 5 and RHN Satellite. 

TO:
Log into the RHN website (rhn.redhat.com) and download the distribution ISOs for Red Hat Enterprise Linux 5 or Red Hat Enterprise Linux 6 and RHN Satellite. 

2) 
FROM:
Register a representative machine for each distribution type, or channel (such as Red Hat Enterprise Linux 4 or 5), to the Satellite. 

TO:
