I'm about to build a couple more worker nodes and it got me wondering whether I should migrate to a newer Linux distro. My current cluster is running on RHEL 6.x, but over the past couple years I've noticed changes to Bro that temporarily required installing newer versions of CMake than RHEL 6.x originally supported. RHEL 6.x eventually broke the mold of not breaking binary compatibility around RHEL 6.6 and moved to a newer CMake which made the RHEL packaged CMake Bro compatible once again. As such I'm wondering if there is anything in the pipeline that would break compatibility a properly updated RHEL 6.x/Centos6.x. I'd rather not maintain separate versions of libraries to build Bro if possible. We're technically a RHEL shop, so I'd probably be looking at RHEL7.x, but I could look at another distro that is more aggressive with running newer kernels and software libraries if necessary. Thoughts?
