I was wondering what feedback might be offered by the CentOS community on their experiences using Scientific Linux?
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!)
I was once a WhiteBox Enterprise Linux user and switched to CentOS 4 without issue, and am assuming that I might need to do something similar if we decide to go this route.
Any feedback is appreciated!
I had to complete a new VM Host machine before CentOS-6 was ready, so I used SL-6 as the underpinnings. It simply worked, once I ironed out a couple of unrelated hardware issues. It auto-updates and lets me know when that's been done, but it doesn't reboot unless I want to, so there's little risk in allowing the updates. Auto-update can be disabled if you prefer.
So far it has been flawless. It's managing two very large software RAID-6 arrays and 7 Guest VMs on a dual-Xeon Supermicro motherboard.
All of the VM Guest OS's are CentOS-5.6 which works well for my applications. I may or may not upgrade the Guests to C6, depending on need. CentOS has been so reliable that I'm reluctant to move to a different platform. I've used Ubuntu Server and it works well, but I'm more familiar with the RHEL way of doing things so I'll stick with CentOS.
One thing I don't know much about is an in-place upgrade of C5 to C6. There are some under-the-hood differences that must be taken into account, which I haven't looked into.
YMMV, Chuck
in-place upgrade of C5 to C6 will be most likely impossible. To many changes of how thing work.
