Doing a 'yum update' will effectively give you a 4.1 system.  You can 
think of 4.(n+1) as being 4.n with all the errata up to that point 
included.  Usually a point release will have an updated installer & 
installation kernel, but since your machines are already running this is 
irrelevant.

Best,
Erik.
