and probably breaking Production.</span></p></div></div></blockquote><div><br></div><div>Fedora doesn't say "don't use our stuff". That seems to be a management line :-) I have more issues with ancient crap lying around only getting security fixes (RHEL4) or bug and security fixes (RHEL5) than still getting new hardware patches as well as bug and security fixes (RHEL6). I ran fedora as public facing servers for years because it was where the best and most current security tools were found. Selinux in RHEL is 2-3 years behind. The long support releases like RHEL are for business who never, EVER upgrade anything and are relying on 10+ year old applications for their core business that are not under active development. I get the allure but no code is perfect and it ALL requires updates over time (except the software that ran the space shuttle - only 7 mistakes in 20+ years of use. Not bugs or crashes. Mistakes. As in all the processes were proven mathematically before coding began. there were 7 mistakes in implementation. NO errors, failures, bugs or crashes ever!).<br>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">RHEL is a bit different from other distros as it focuses on stability by NOT updating every package to the latest upstream version over time. Instead it starts
with a given upstream version of a package then backports bug and security fixes into their version to help insure you’re not suddenly not changing underlying tools used by your static applications. For most businesses this stability is an important consideration
which is probably why it is so successful.<u></u><u></u></span></p>

No, I'm at UA (University of Alabama main campus) in Tuscaloosa. I'm the primary Systems Engineer for Linux Systems, and the backup guy for virtualization. Luckily, the HPC stuff gets managed by someone else for the most part.<br>
How big of a deployment do you have?<br>
We've got 250+ datacenter Linux systems, and another big chunk for HPC/research.<br>
Most of the datacenter stuff runs SLES, with a handful of other distros thrown in the mix because of vendor requirements.<u></u><u></u></p>
