Does CentOS now only support user request tracking by email? I cannot 
find this thread on the CentOS web site...

My computer has 4 GB Patriot memory - the maximum amount the motherboard 
allows. Using  command "top" shows less than one percent of CPU and 
memory are in use. The computer is idle. I am using a 1 TB WD disk for 
CentOS 5 and a 2 TB Seagate disk for CentOS 7. No RAID.

On CentOS 5, I use command "su" to show a root shell. On CentOS 7, su no 
longer works and I use "ssh root@localhost" instead. (I have not tried 
SSH to access my CentOS systems remotely yet.)

Concerning a previous comment: I did not modify the hardware likely 
causing this problem. I only have to switch between both disks - 
described above - to boot CentOS 5 or CentOS 7. My suspicion is "yum 
update" using numerous official and unofficial "repos" installed 
something causing this challenge. The login screen of CentOS 5 for user 
name and password still works fine. By the way, we develop software 
(NMRanalyst) and I try to keep a CentOS 5 system alive so we can test on 
it to claim our software is supported on it. When I don't get further 
suggestions, I likely re-install another disk with CentOS 5 - this time 
using only official repos.

ThanX for all suggestions!
