I do not understand the question, the Compatibility ez must be especially with web server, php version, or even database. In any case, I confirm that I work with a centos VM for a long time to develop ezpublish site. and I had no worries.

Hi Romeo, Abdelkader is correct. As long as you have the "core" systems in place (eZ, PHP5, MySQL >=5 etc) you are set.
I use CentOS although with an older eZ version, with no problems.
For your purposes, there should be no difference between RedHat and CentOS, for all intents and purposes, they are the same. CentOS versions track RedHat versions, CentOS is pretty much RedHat, but cutdown for server environments (although I still run KDE off it myself)
