Sun Considers dual-sourcing Solaris Under GPL3 198

foorilious writes "In his blog, Sun Microsystem's President and COO Jonathan Schwartz discusses the possibility of dual-licensing Solaris (and perhaps the rest of their software suite) under GPLv3, in addition to the CDDL, which is the OSI-approved license under which these products are already available, but generally considered to be incompatible with the GPL at some level. Though this could mean an opening of the floodgates to a lot of sharing between Linux and Solaris (among other things), it's worth mentioning that Schwartz has speculated on exciting things in the past (such as porting Solaris to IBM's Power) that we subsequently never heard another thing about."

      The thing is, you could still get a lot of interesting tech from the solaris OS without necessarily taking anything from the kernel. Remeber, that Linux is simply a kernel. It doesn't require that all software run on top of that kernel be run under the same license. If they simply release the Solaris kernel, it probably wouldn't have meant much to Linux, because Linux already has a pretty good kernel, and I'm pretty sure they'd be a little incompatible anyway. I think the main thing that will help is the applications that run on top of the kernel, that Sun may be releasing.

      Probably as well or better than the kind of sharing that puts OpenSSH into every Linux distro.

      Imagine Debian on UltraSparc with a Solaris kernel.

      Imagine Sun Linux kernel modules. You don't really think a practical person like Torvalds would turn any of that down do you?

      This is actually what i posted about before. Any project that licenses GPL2 is going to feel an increasing pressure to go GPL3. Some of them will just be assimilated by the "...or any later version" suggested language. Some, like Linux, which are GPL2 only, will start to look like isolated islands of ancient code, shut out from all the modern goodies.

      The Linux kernel probably won't ever be GPL3, because the license it uses doesn't contain the forward-compatibility clause that the FSF's software does; however, all the GNU utilities (including, I believe, GCC) will be GPL3 and/or GPL2, because they have the forward-looking clause.

      So really what it would allow a person to do, is produce a GNU/Solaris as opposed to GNU/Linux -- an OS that would have the Solaris kernel, wrapped in the GNU utilities, without the Linux kernel. I'm not sure if anyone would really want that, because I'm not sure that it would be compatibile with either existing Solaris or existing Linux software without rewriting, and it generally seems to be a solution looking for a problem (not unlike GNU/Hurd).
      • I would definitely prefer that Solaris have the GNU versions of most of the command-line utilities. I have a hard time going back to the "old" versions that Solaris has, which are often missing functionality that the GNU versions have. Just the ability to put options to commands after the filename arguments would make me happy.
      • Personally, I'd LOVE a GNU/Solaris distro.... the Solaris kernels are extremely robust. I've had very bad luck with Linux all through the 2.6 series. Even the stable versions have had constant security patches, requiring reboots and downtime. I hate downtime.

        FreeBSD with the GNU utilities is one possible replacement, but it'd be nice to have a kernel that's both extremely robust AND scalable at the center. FreeBSD is very solid, but it doesn't (yet) scale like Solaris does. Linux scales, but it's not

    One of the least discussed but largest changes in GPL3 is the explicit mention of patents and how patents (if found to be violated) would effect the work as a whole. This is similar to the IBM Public License and is one of those things that I'd imagine would give a corporate lawyer warm fuzzies. Sun and others may find this change so compelling that they'd be willing to give more attention to the GPL3 than the GPL2, which strengthens it further (since these companies want the flow of information to go both).

      You have to be careful here. Solaris used to be called Slowaris when run on Intel machines, because it was designed for much more powerful hardware. A lot of features that are hardware supported on a SPARC machine had to be reimplemented in software on Intel machines.

      Another common vector for the "Slowaris" comments is the early days of the Sun framebuffers. Sun was one of the first vendors to do away with text mode all together, and emulate it entirely in software. The upshot is that Solaris SPARC machines have the best looking, smooth font, conole you will ever see. The downside is that the 100 MHz beasties that started this practice had a bit of trouble keeping up with the needs of the console rendering.

      Neither of these issues has been significant for a very long time. I haven't heard anyone call the OS "Slowaris" in almost a decade. The complaint I hear today is that Solaris is unwieldy and not at all designed with user-friendly setup. Sun keeps trying to fix this with new, prettier installers. I don't think they have a clue though, because the first thing I have to do every time I install the OS is go into the config files and setup the DNS server and default gateway. You'd think it would kill them to ask this info during an install. :-/

      One of the design goals for Solaris 10 was for it to be not more than 5% slower than Linux for a range of single processor workloads where typically in the past Linux had been faster (on the same hardware).

I think what a lot of GPL users want is for their code to stay GPL, and for changes made to the code by others to be brought back upstream, so the whole community can take advantage of the changes. I think that's what GPL V3 is trying to accomplish.

        • If you wanted to be the least restrictive you'd put it in the public domain. I really don't see the point of the BSD license in most cases.
          • The difference between BSD and the public domain is that with BSD you still maintain copyright over whatever you release. Others can do whatever they want to with it, but you still have the copyright. If you release something into the public domain, I don't believe you retain any copyright to whatever you release.
            • No, but why would you want the copyright? So you can relicense it under another license? There's no point, since either BSD or public domain is liberal enough that you can do that anyway without holding the copyright. So you can stop others making derivative works? But the license lets them anyway. There's no point keeping your copyright if you're not going to exercise any of your rights under it - and BSD allows just about everything you have a right to prevent under copyright.

    If SUN plans an OSS strategy they are certainly NOT going to GPL their powerhorse Java. Solaris is nearly just as impressive from a technical standpoint. It's probably that Solaris doesn't have the numbers attached to it SUN would like to see. So they probably guess it could prove itself as OSS, since Linux is winning in the custom Unix market at all fronts.

    The GPLv3 is still in draft form. It doesn't actually exist yet. The version on the FSF webpage could be better classified as a "beta" release (I think that's what Stallman considers it).

    It's a little early to be saying "I'm going to be using the GPLv3!" Yes, they're working on it, but it's not actually out yet. The optimistic "release" date is November of this year, with the expected release date being early 2007... It's just not ready yet!

    However, thinking about the current draft and any problems you have with it is encouraged. They want comments still, there's still time to help change the final draft. Saying "I'm going to use the GPLv3!" is still premature. Wait until it's actually finished, then decide.

    I have to admit Sun seems to have some positive swing lately. They're selling some hardware again. Their open source policy finally seems to be bringing in new customers, after years of shooting themselves in the foot with weird licenses, inconsistent marketing and plain corporate stupidity affecting all their business units.

    Their strategy of the past years has been very ineffective. Java has become a multi billion industry, Sun has invested hugely in it but they have failed to cash in on it directly (I suspect they barely break even). Also it hasn't driven hardware sales that much. Their main competitor on the other hand seems to have a very succesful Java strategy. IBM is leading the way in application servers, IDEs (eclipse, rational rose) and middleware with basically the whole industry eating out of their hand, including most JCP specifications committees. On top of that they also sell the hardware & support to go with the software. IBM loves Java!

    Then the whole x86 solaris thing has come a long way too (from 'hey it's free now but we support it for a fee', 'oh wait we don't do that anymore' to 'oh well lets open source the whole thing and forget about it' to finally 'hey x86 solaris is really important to us'). I mean, what do they want?

    Sparc sales have been a disaster for the past years with people basically favoring IBM power and x86 with linux. They may be laughing at intel for itanium but they have one thing in common with intel: x86 is driving sales for both of them. Sun has a few next generation architectures on the shelves which no doubt they are going to try to sell. These chips had better be way better than the competition (and their mediocre current offerings) or otherwise whatever spin they put on it won't work. Personally I'm not convinced yet. Their two operating systems (solaris/linux) & two architectures (x86/sparc4 aka niagra) policy is going to continue to confuse people. Sun seems to think the combinations can coexist without affecting each others marketshare. I don't. Confused customers will look to IBM and others.

    To me Sun still is a company in trouble. Maybe a few of their business units are recovering (finally) but that still leaves large parts of the company not performing very well.
