I'm a long-time Centos user, and am basically happy with CentOS. I understand there are delays getting EL 6 out. We have been long anxious to roll out EL 6 as soon as it's ready, but our time window for rollout is looming and we will need to act. (for business reasons, we need to rollout over summer, before Aug 1, we need to start regression testing now!)
Hi !
Here, we have a cluster of 8 nodes that we just deployed in RHEL 6 (the real thing, 14 k$/year). And with that, came other servers (router, test servers, developpement servers), and I wanted to have also the same OS. While waiting for C6, I installed an unsubscribed version of RHEL6, but it was troublesome to install packeges. So for those servers that were already installed, I switched them to SL6 without having to re-install, and it went great without a pain. I installed some other servers with SL6, and didn't noticed any difference.
I plan to switch those SL6 servers back to C6 when it's out, for uniformity reasons, I don't anticipate any problems then.
Regards,
