.comment: How Distributions Can Succeed (and help Linux take over the world)
Another Little Step for the LSB

Comments are being accepted for the
latest proposed incarnation of the Linux Standard base. I have three
proposals that would make life easier:
-- The existence of /opt as the
parking place for things that sensibly call for isolation. Desktops
are an example, because these are frequently updated with the latest
code, and it's easier to back up a directory that contains all of it
than it is to go through the file system and pick out all the pieces.
Failing this, create an exception for self-contained packages in
/usr/local.
-- Settle on a standard package
management system. It has to be one that traps and includes the
results of "make install." Everything necessary for this
exists; it simply needs to be incorporated.
-- Go into some detail. The effect
ought to be that a competent Linux hand will be unsurprised by what
he or she finds in the file structure of any Linux system.
The effect would be a Linux Standard
Base with some meaning. While of course there will always be
different versions of practically everything, there would be no doubt
as to where they're found, and there would be a disincentive for
distributors to take flyers off into /var/X11R6 and things like that
(unless it is decided that all should).
I can anticipate some of the whines:
"But that about choice?"
I'll give you choice: You could then
choose to run any package on any distribution. Those who are kind
enough to produce binaries of their programs would not have to go
through hell to do so -- it'd be pretty much down to a version for
each of the several common versions of glibc. Support would be less
of a headache, because it would be the product, rather than the
product on a particular distribution, that would be supported. This
means that the authors would get to discuss their application, rather
than its packaging (which is half or better of the support problems
-- check any mailing list). And there would be fewer compilation
problems from distribution to distribution.
But If the Distributions Were All
Alike . . .
When you buy a distribution, what are
you really seeking?
Well, CDs containing a kernel and
everything else that makes a Linux system, because you don't want to
download it all yourself and unless you are one of a relatively few,
even if you did download it all you wouldn't know quite what to do
with it. So there is the convenience of that which you can get online
for free, more or less, all in one place. You're getting docs of
quality varying from helpful to useless. You're getting some
vestigial degree of support, though not much over what you can get
online anyway.
And you're getting installation and
configuration tools.
What would change if there were an
absolutely iron-clad Linux Standard Base? Nothing. Distributions
would still ship a CD full of Linux, because what you're paying for
is the convenience of not having to download it all. They would ship
documentation, and some of it would still be useful and some of it
would still be awful. They would ship their own little configurators
(some of which are good and some of which are linuxconf).
Actually, that's not quite right.
Distributions would have to get better, but they'd also be able to
get better. With a standard base that's an inviolable known quantity,
the choice of one distribution over another would be made through the
quality of the documentation and the quality and flexibility of the
installation tools. These are perfectly salable, though usually
overlooked, additions to the value of a distribution. Instead of the
situation as it exists today, where many users are afraid to get
binaries from anyone other than their distribution because otherwise
they might not work, they would be able to get them from just about
anywhere. This would free up distributional resources for the
production of better tools and docs.
It would also free up distributions to
specialize. I think that it's wonderful that SuSE has remained
committed to the desktop (though they offer a server edition as
well). Wouldn't it be even better if as part of the installation
routine, the choice of desktops offered by SuSE were made with
screenshots, a little about the applications that are native to each
desktop, why you might choose one over the other (XFCe for
low-resource systems, for instance), and so on? Mightn't it be good
if, by the time the new user has installed a distribution, he or she
has learned something about the Linux being installed?
It's also great that Caldera is going
after the enterprise. Their tools have already become somewhat
focused -- WebMin is not something a typical desktop user would
employ frequently, but a sysadmin might use it a lot absent fluency
in the details of editing configuration files -- and Caldera would
be free to make them more so.
With it all would come less incentive,
in fact, a community-based disincentive, to change other things.
There really is little reason to screw around with rc.d, but lots of
reason to come up with a bulletproof X configurator or an easy way to
set up a Samba share.
Nor would this reduce the
participation of distributions in project development. Many of the
commercial distributors have people on the payroll whose sole job is
to work on free projects, be they KDE or Gnome or WINE or something
else. It makes sense that as distributors specialized they would
probably choose to pay people to work on areas where the distribution
itself is focusing, but there's nothing wrong with that. The fact is
that to have a star developer with your company as part of his or her
email address is a little like having a star basketball player
wearing your shoes. It's a prestige thing. With less time and money
spent messing around making your distribution incompatible with
everyone else's, there would be more of both to devote toward
improving the operating system in general.
The greatest advantage would come to
Linux itself. There has been a subtle but insidious forking of Linux
that, if it continues, will cause its hope for widespread adoption to
disappear in a virtual Tower of Babel. Individuals and companies who
are accustomed to getting a Windows application and that's that
(okay, Windows itself is forking and may well get stuck in its own
CE-ME-NT) are likely to be less patient than some of us have been in
the lack of binaries for our particular distribution. (Just this
week, I sought to add the estimable Plugger to my notebook, only to
discover that there is no glibc-2.2 binary; yes, the source is
available, but it requires the Netscape plug-in toolkit, and I've
about had it with feeding details of my life to yet another Netscape
form.) With a defined Linux, as opposed to [Distribution] Linux, this
problem would disappear (though glibc version incompatibilities will
forever be with us, developers would probably welcome the change).
All this would require a solid LSB to
get published rather than just talked about. It would require the
compliance of distributors. It would require a little vision,
abandonment of the idea of knocking out the competition right now and
instead understanding that if there is ever a one-distribution Linux,
it won't be a commercial distribution and it won't be widely used.
Linux is under fire, and it will get worse. A solid definition of
what it is that constitutes Linux, plus a variety of distributions
that employ different ways of utilizing it, would assure that Linux
survives the onslaught.
I don't think anything else will.
