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,
