The opscenter documentation says that Centos 5.4 and 5.5 are supported. http://www.datastax.com/docs/opscenter/install_opscenter#installing-opscenter-on-rhel-and-centos
Is 5.6 not supported?
When I take a fresh 5.5 install and do a 'yum update', it updates the kernel and the centos-release package among other things. Assuming that I want to a be stickler for versions, is there something I should do to prevent 5.5 from going to 5.6?
