Can GNU Ever Be Unix? 217
An anonymous reader writes "The question isn't whether Linux can be certified as Unix. At least some distributions no doubt can. But who would pay for it? And is it worth the trouble? Jem Matzan asks these questions on NewsForge, and reminds us that the Open Group, not SCO, owns the Unix trademark,"

This is particularly evident when you notice that the major improvements in some recent version of Solaris (8 & 9, but not 10 apparently) is to add more open source software and stability improvements.

I think it is almost certain that some distro of Linux could easily pass OG's test suite. It is also almost a certainty that FSF/GNU would never opt for it on religious grounds.
The rest of the thread is now available for stupid /. jokes.
In Soviet Russia, The Open Group petitions GNU for certification.

But I think the more significant point is that it's not FSF/GNU who would have the most incentive to get a distro certified as Unix. As the article pointed out, it's probably the hardware companies like IBM and Sun who would find it worthwhile.

IBM have specifically taken a hands-off approach to Linux. They have team members contributing to the 'greater' Linux source trees, but there's no sanctioned 'IBM' brand of Linux. They don't want nor need an 'official' IBM version of Linux.
The reasons for this are complex.

I have been saying that for several years now. UNIX is all but dead. The only commercial UNIX likely to still be arround in ten years time as an ongoing product is OS/X. Solaris will have long since joined IRIX, Digital UNIX and VMS as O/S you can still buy and occasionaly see a minor upgrade for it.
There is a basic set of core functions that O/S do and this has not changed in principle for over a decade. Log based file systems, threads that work etc are now standard, but none of this was new ten years ago.
The interesting stuff all takes place either above or below the O/S layer. .NET, J2EE etc are where interesting stuff is happening.
At the driver level I think that both Unix and Windows have the model hopelessly wrong. We have at last got past the point where we have to recompile the kernel for each new driver. But drivers are still mostly executable code while the differences between devices of the same genre are with very few exceptions the type of thing that can be described by code tables.
I would like to see device manufaturers get out of the device driver writing business, have a genuinely generic driver in the O/S and discover the repetoire of a particular device by reading a configuration file - preferably one that can be read from the device. From a pragmatic point of view XML would probably be a good match for the task since you would inevitably need structured data and a way to extend the basic data structures.
Unix once had this with the printcap and termcap files. Unfortunately people just seem to be unable to resist turing complete code.

This must be an Amiga from a parallel universe you're talking about.
I still remember the joy of the developers when the GCC compiler was ported to it, but it was not until 1990 if I remember correctly.
You were not talking about the 2500UX, were you? That's another thing completely.

Case in point. I'm at a conference. Someone asks me what I use. I reply "Unix". Suddenly their eyes bug out, their ears turn red, and they scream, "no you're not, GNU/Linux is not Unix!!!" Then I explain that I'm not running Linux and they're heads finally explode.
Okay, that's a bit of hyperbole, but in my experience most GNU advocates (a distinct breed from Linux advocates) take great pains to enforce the Open Group's trademark.
UNIX matters (Score:5, Interesting)
Back in the days, around 1995, my friends and I were looking for any UNIX to put on our machines to learn. We tried an old copy of SCO Unix which didnt work, and were busy snooping till we found Linux just as it was getting popular online. We got into Linux because we were out looking for UNIX.
Nowadays I've got AIX and Solaris on ultrasparc to play with, so I can finally brag about knowing 'unix', but would be real nice if Linux is called UNIX. Even though SCO has spilled cold water on the brand name, it still carries enough weight, and maturity of two decades, to get attention. Linux is still new to the scene, and UNIX has carried the full weight of the Internet since its birth... that means something.
Linux means alot more now, so can UNIX be Linux, or at least its former self? Thats possible, if Linux is branded UNIX, and UNIX can once again claim to be a popular flexible modern OS. Cant do that with SCO Unixware.

Sure, it wasn't unix technically speaking. However, if you allow a certain 'artistic license' like we do for OS X, and add in a 'handicap' since this was a 16-bit 7Mhz machine usually with 1MB RAM or less, we can start to see just what AmigaOS was. IMHO, it was closer to a personal version of GUI-enabled Unix than OS X has managed yet. Technology has moved on, but I still miss the productivity I had on AmigaOS.

UNIX is the actual operating system (which Linux has made a very powerful and capable clone of). It could be OS X, Solaris, AIX, *BSD or whatever. Fine, now I have my UNIX station, what am I going to do with it ?
Of course, I'm going to run GNU software on it. That's the whole point of running UNIX, the GNU software. Killer apps like the X server(s), Emacs, ftp/web/dns servers and virtually any other software you could ever imagine. I'm running UNIX (or clones) to run the GNU software.
I'm curious, does anyone else share this view ?

Of course, this is propably caused at least partially by Linux's success - Linux is drawing all the the good OS programmers.
The dev mailing list archives seemed depressingly empty when I checked :(.
Ironically, the Hurd should (at least in theory) be a lot easier to modify and develop. I wonder if I should give it a go... Maybe someone could port the Mach microkernel so it would work under Linux (or put a "Mach emulation layer" into the kernel) ? This would allow the Hurd to use the Linux device drivers, and allow people to try it without needing to repartition (you could use files as block devices via the loopback device). It would be just the kind of kick this project needs...
Of course, you could make an user-mode Mach emulator, but that would likely be pretty inefficient. Or would it ? Hmm...
Great, I already have all kinds of projects underway, from a roguelike for Java to a Usenet picture grapper with a web interface, and now this tought just had to pop in ;).

The difference between what the HURD has designed and the various efforts to implement them in Unix like operating systems is in user space. The HURD allows (or will allow, once its done) per-process overrides of any system call. LUFS simply allows a user space program to tell the kernel how to represent a device. With the HURD, there is no reason why another user will even see the results of your translators.
What I don't understand, is how the HURD is so late when it has these features. Creating or modifying a new system call should just involve installing a translator, testing it, and at worst logging out. No rebooting to test a new kernel feature.
Could Linux be an extension to UNIX? (Score:2, Interesting)
Not only would this increase the capabilities of Linux but it could also serve as a way to bring UNIX applications into the Linux world with little effort. Once this is done, Linux can then efficiently replace UNIX itself.
What I believe the industry needs, is a "modern UNIX" that can compete with Windows from not only a user point of view but also a technical one. We are starting to come to the point where not only is UNIX but Linux is starting to become "left behind" by Windows through
