First Look at RHEL 5 - From the New, More Open Red Hat 220

Posted by ScuttleMonkey from the reinvention dept.
Susie D writes "Red Hat Enterprise Linux 5 was released today, and Linux Format has an in-depth first look (with screenshots aplenty). With RHEL 5, Red Hat aims to become even more 'open', by using a shorter and clearer SLA, improving community involvement through its Knowledge Base, and providing the new Red Hat Exchange. But what you really want to know is, yes, it does include XGL for fancy 3D desktop effects."

      And that's a good thing. Red Hat likes CentOS. Between CentOS, RHEL, and Fedora, there are three "Red Hat Family" distributions that meet three very different sets of needs.

      Every CentOS install is an install that is within the Red Hat family. For people who don't need to be able to call up Red Hat and ask support questions (but who still need an enterprise distro), CentOS is a great choice.

    Now, I don't see any reason not to have XGL on the desktop - in fact it's a huge boon. But is it actually necessary on a server? Or more to the point, isn't it a horribly bad idea on a server? You should be running as little as possible on any critical machine... And if you have so many windows open on your server that you need a 3D desktop to manage them, perhaps you should be running all that shit somewhere else. And if you're using RHEL for a desktop system, for any reason other than being able to test things before deployment, you should have your head examined.

      Actually there are few more reasons to use RHEL (or maybe deriatives like CentOS) on workstations.

      http://www.redhat.com/rhel/desktop/ [redhat.com]
    • Many worstations use RHEL because most proprietary apps will only target it and or SuSE enterprise. Also companies like Dell will only support their workstations if they run RHEL. Obviously mute if you only run free software and firefox.
      • s/mute/moot/ but besides that, my point is that most workstations don't even have proprietary apps on them. If you need it, fine, run it. But most people don't. Obviously there is always that one person, or that one company, that will need to use it.

However, AIGLX required modifications to the video drivers, and ATi and nVidia took some time in making the necessary changes. That's why XGL caught on initially: because unlike AIGLX it worked on mainstream 3D cards. (These days, nVidia's current drivers

    I used Redhat back in the day, just before I became a die hard Debian user. I'm wondering what exactly should drive me to want to switch to Redhat at this point? They seem very fractured to me and the whole "Enterprise" setup with a "free version where we develop everything" or whatever doesn't strike me as very appealing.

    But I'll grant, I'm somewhat ignorant of the whole Redhat thing these days. Anything I should be enthralled by and jump into Redhat for? Not trying to bait or troll. Would seriously love to hear what people with more recent experience of RH have to say (especially if they're also familiar with Debian and others so they know where I'm coming from).

      Things are different these days. The main thing you get from being a paying customer of Red Hat is long-term stability (i.e., packages stay relatively the same for years, aside from bugfixes), patch rollout, and support from both Red Hat and other vendors. You're probably not in their ideal audience anymore, since general users who want a good free desktop were pointed to Fedora when that project was created from RH9 a few years ago. Now the company's audience consists almost exclusively of corporate types who want support from Red Hat, or who run software that is certified to run on Red Hat but is not guaranteed to work on much else (such as Oracle). Your distro of choice, righteous though it may be, wouldn't suit that audience very well because if there were problems, there would be no one to blame.
    • There is no reason to switch to RHEL unless you have an enterprise to run. It is a very conservative distro (as in not includng cutting edge stuff). It has to be, since stability is what you get and pay for.
      • The downside is that RHEL tends to get stale quickly, much like old versions of Debian. RHEL4 has very old php, perl, python, mysql, etc. If you install modern web applications, RHEL frequently does not meet the minimum requirements. What RHEL really works well for is installing applications that just run and run, that don't need updating frequently. Unfortunately, we live in a world where you you usually NEED to upgrade applications due to vulnerabilities that have been found in old versions of software. R

      Well, RedHat's business model is centered around providing support for a version of the Linux operating system and its programs. Businesses don't want to deal with a large cloud of people anywhere and everywhere in the world when it comes to requesting improvements, fixes, etc. They want to go to one place and point a finger and say, "You! Fix this!" That's what RedHat, Inc., is. The people you point the finger at. They build, package, and distribute a specific version of Linux and its programs and utilities. They make them work together. They provide security and bug fixes.

      You can argue which distro is better until the cows come home. But when it comes to a corporate adoption, you'll need a RedHat, SuSE, or some other company like that to provide the target for finger pointing.

    "RHEL used to come in four main strands: ES, AS, WS and Desktop, although the Desktop product was sold as a pack of ten clients along with a copy of RHEL ES, the server version. With RHEL 5, Red Hat has swept all of that away in favour of a simpler structure. Instead of distributing the four sets independently, Red Hat will provide only two main sets, referred to as Server and Client. Subscribers are issued with installation keys that pre-define package manifests depending on the subscription level."

      Usualy for things like that (and I didn't check, and don't quote me), is fairly simple. When you pay redhat, what you're most likely buying is the support, not the product. So if you install more client than you paid for, and you called redhat and they somehow knew about it, you're sorry out of luck.

      That quite the abstraction of how it works, but you get the idea.

      There is no limit on downloading the source. When you buy RHEL, you buy the *binaries* and you buy support. The GPL explicitly allows charging for binaries. You are even allowed to charge "reasonable" media fees for source, but Red Hat very kindly makes the source free as in beer. You can compile the source yourself, or let http://centos.org/ [centos.org] do it for you.

      The GPL is about *freedom*, not price. RHEL gives you full freedom. And while you can't get official RHEL binaries for free, derivatives based on the source are available that are free as in beer.

      While an individual or small business has little reason to buy RHEL, an enterprise has good reasons. You get a highly stable platform with security patches for a long period of time. You get support. You get someone to blame when things go wrong. As an individual, you might want to try Centos and get familiar with it. You never know when you might want to work for an enterprise that uses RHEL. As a small business, you can start out with Centos, and if your business takes off, scale right up to RHEL with minimal hassle.
