Sorry - I typed K12Linux when I meant K12LTSP.  I guess I need EL6 then. 
  I have two servers right now - one of them is at the school and is 
slated for retirement.  The other is here on my desk at the office.  I 
could do an install from scratch.

My main requirement is to support the old 900MHz Celeron's we're using 
for TC's.  As I've been reading the list, it looks like I need to be 
careful about what I upgrade to.  EL6 supports old clients, right?
