Rob writes "The wait is almost over. It may have taken two weeks longer than Red Hat would have liked, but Red Hat Enterprise Linux 5, the updated version of the company's commercial Linux platform, will be launched along with a bevy of new products and services on March 14. The delivery of RHEL 5, the fourth major commercial server release for Red Hat, will better position its Linux against Novell's SUSE Linux Enterprise Server 10 as well as Windows, Unix, and proprietary platforms. RHEL 5 has been cooking for more than two years and includes changes to the Linux kernel. In addition to the support for the Xen hypervisor, RHEL 5 also has an integrated version of Red Hat Cluster Suite, the company's high availability clustering software, as well as support for iSCSI disk arrays, InfiniBand with Remote Direct Memory Access (RDMA), and the SystemTap kernel probing tool."

      I don't think your criticisms should be aimed at RHEL. If you wanted new packages over stability or wanted to be able to force upgrade then you picked the wrong distro. You are not their target audience.

      If the stability of fedora is enough for your needs maybe you should look there instead?

        I agree with Martin's comments here. RHEL is Enteprise for a reason. It has long term support, it's stable. One might liken it to Debian stable, although it tends to be a bit more cutting edge than that, although not quite as cutting edge as testing, I believe (I could be wrong here. It's not exactly like I have done a one for one comparison of every package, so feel free to correct me).

        I've been running Red Hat in an "enterprise" environment for about 8 years now. I've seen it go from an upgrade every 6 months to not needing an upgrade for the life of a box. Taking a look at our satellite server, I see 210 machines still subscribed to the RHEL 3, and even 13 subscribed to 2.1 (itaniums, hey, they still run!). These boxes are stable and secure, and I'm happy with that. They are performing their functions.

        No doubt, it's not for everyone. Many people can't afford it, including myself in my personal life (alright, I could, but I really don't feel the need). Fedora is fine for those. Ubuntu is fine for those. Whatever other version you like is fine for those. If you want it to run with minimal upgrades, you stick with something that has support in some fashion for a long long time afterwards, like RHEL, where you can get security fixes for 7 years after release.
        • I agree with you and Martin. I have run several dozen RHEL2, 3 and 4 boxes in the past. While RHEL isn't my distro of choice, there's not much wrong with it. Debian just does some things slightly better.

          If you color in the lines as far as packages go, RHEL is a remarkably stable OS. Coupled with enterprise support that most PHBs will like, it is a fine arsenal in any sysadmin's cache.

Not only that, but the behavior is not one I found reliable.

          If you run an enterprise application, stability is critical in terms of both operational reliability and package versions. While I agree with you that some of the higher level applications that could be kept more "fresh", Enterprise Linux targets an audience that tends to run mission critical applications on their operating systems. These companies deal with a number of third party ISVs who certify their products on Red Hat Linux. If software package versions are changing constantly, ISVs will refuse to certify said changes due to the cost of doing so.

          This was one of the problems with Red Hat's pre-Enterprise Linux audiences. ISVs saw Linux as a moving target. I think Red Hat does a good job of freshening what they can with their point releases.

          Simply put, if you need bleeding edge software, you'll need to find it from Fedora or a third party repository. There are a number of repositories out there, AT-RPMs, Dag, RPM Forge, etc. that package applications for Red Hat Enterprise Linux. However, for Linux to be enterprise-ready, core stability (again in terms of versioning and reliability are a must.

          However, it's a bit disappointing that my employers were still paying a support contract on this box but the package updates that were part of this contract were more than 3 years old.

          The point is that, even though the Python package may be 3 years old, if it's still under support, and tomorrow they found a security bug in that years-old version, you would still get a security patch for it.

          I don't think it's too much to expect a little flexibility when you're paying for it.

          That's the thing.. you're not paying for a little flexibility. You're paying for stability and maintenance. It may seem backwards to you but that's the exact sorta thing that most "enterprise" customers want. If they offered the sort of flexibility you're looking for, that would mean supporting multiple different versions of different packages within a single distro.

          The reason they can offer such long-term support is that every user of every package in that distro is running the exact same version. It would simply not be economically possible for them to offer 7 years of support on a product if they allowed people to run whatever version they wanted, even as an option.

          I should say that I didn't buy or install this box. It was bought for a biological research institution and the guy who made the purchasing decision chose it because it was Dell's recommended choice. RHEL3 may be ancient, but it came on a fairly new machine, bought in early 2006, so they were obviously still selling it.

          That seems a bit off. By early 2006 any current Dell would have been certified for RHEL4 (which itself was released early 2005). As a aside, license for RHEL are valid for any currently supported version, so even if it came imaged with RHEL3 you had right to install RHEL4.

          It's fair enough that they focus on rock solid stability over new packages. However, it's a bit disappointing that my employers were still paying a support contract on this box but the package updates that were part of this contract were more than 3 years old.

          The updates are not three years old. There was a new update published this morning. The base versions are old, but that's a feature, not a bug. When you're running production systems you want a stable platform with a reasonable deployment cycle, which is where RHEL excels.

          I don't think it's too much to expect a little flexibility when you're paying for it.

          When you pay for one of the enterprise platforms you're paying for stability not flexibility. It's actually more work for them to backport fixes to older versions than to blindly package newer ones, but new versions mean new bugs and incompatible changes. Some of us pay good money to avoid it, and RPM is flexible and easy enough for the few cases we actually need a newer version than what Red Hat ships stock.

    • RHEL is certainly a distro that is aimed at stability rather than the latest features. It is Red Hat's policy that they will not upgrade any package past the minor version that originally shipped with that release. So if it shipped with Python 2.2.3 then it will never go past 2.2.x. They will backport security or stability patches from later releases if necessary.

      If that's not the policy you're looking for in a distro, then RHEL is not the distro for you. That said, I have had lots of luck in compiling SR

    • It should be noted that there are third-party projects to add the flexibility and newer versions you want, like CentOS Plus [centos.org] (includes PHP 5, Postgres 8, MySQL 5, and others) and PyVault [python.org] (Python 2.4).
    • Welcome to RPM hell.

      Which is why I switched to Ubuntu and FreeBSD long ago from redhat. The conspiracist in me thinks rpm was invented as a way to keep you on the upgrade trendmill. I spent lots of money in the past upgrading linux distros before I had high speed internet access and could apt-get or use the ports. RPM is truly terrible and yum does not solve anything other than to download some other packages that might be required with it. Upgrading is still a nightmare.

      We had similar problems. However all you have to do is when you install the newer version of python, do make altinstall instead of a make install. When you need the newer version, you just do /usr/bin/python2.4 when you start your app. Python takes care if it all. Really simple.

      • Centos has another HUGE advantage over the base RHEL - the CentosPlus repository. With Plus, you can grab php5 without needing to go out and grab srpms from fedora and make all sorts of manual changes to make it work, and building / maintaining your own packages.

        RHEL could gain a LOT more converts and increase value with their own version of Plus. Plus gives you the best of both worlds.

    One thing Solaris does well which Linux is still struggling with is crash dumps and crash dump analysis. I know it is easier with Solaris due to the integration between the OS and the hardware, as opposed to say Red Hat and a variety of supported vendors, but is definitely a nice thing to have. Especially if a system crashes and you bring it back up without a good analysis of what went wrong - you might have a $10000 system for the business unit (with everything included) yet if you don't know why it crashed, you're always nervous about the box. The Linux core team talks about having to get to the enterprise level, and Linux still has a way to go in terms of this, to get to the level of Sun and vendors like that in this respect.
