I don't see how this is a "base" issue over a "dependency" issue still.

Dependency checking is not magic.

But this is a case of respec'ing something that's already done by X.

Arguably, yes. And, if it's small middleware, I don't have an issue
with considering it's inclusion. But, libncurses amounts to what, 4M or
so? That's definitely borderline, but arguable. X, I would have to
differ on that point, based on size.

To me, that's a scary base. It sounds like your only talking about ISVs
who want to do GUI workstation environments if you want to consider
that. If I had time, I would reference the several dozen articles on
why Linux can do what Windows can, solely because it's scalable, and now
possibly headed towards the embedded market.
But, that's the point. The base itself should be flexible enough that
it can be built on by any ISV, if Toshiba said tomorrow that all their
new car stereo's were going to run Linux as the OS, so that people could
hack them... I'd stand up and cheer for Toshiba. It would be a great
day for Linux.
Given, that's a single, maybe not the best example, but the point
remains, there are many people using, and looking at Linux, that would
embrace a standard, but not if it's a huge thing that requires 100M.
(anyone working on something like that? What about Lineo? anyone know
what it's code looks like size and compliance wise?)
I don't intend on addressing what seems to be the dominate argument
here, that "almost everyone needs X" because I don't believe it. I
think it's short sighted. If the LSB requires X, then most ISP's, rack
mount system manufactures, and many "Linux device" companies will be
very far outside of standard compliance. Take any one of those markets,
and exclude it, and I feel it will be making a mistake.
Consider any major internet site that runs Linux (excite.com, salon.com,
amazon.com, etc..) really should require X on all their servers?
Obviously no. Some DB ISVs also will not need X. I just don't see how
it's absolutely necessary that it be in a "base" set.
By making the LSB include X, your excluding all these people from having
a useful standard to draw from.

Again, that's just a "let's throw everything including the kitchen sink
in" mentality. And, there is no reason X can't simply be treated as an
optional layer on the base.
Requirements such as X for some ISV software should be addressed. But
they should be addressed through a standard package accounting system.

It's not a win-win-win situation. It's a win-loose-loose situation.
Not all ISVs need X, not all linux hardware manufactures need X, not all
distributions use X (Yes, it's true, one of the strengths of Linux is
all the little nitch distributions, don't write them off so fast), and
believe it or not, probably MOST Linux users don't use X (if you
understand that most Linux users don't even know they are using Linux
when they send mail through their ISP, or load a web page from a Linux
server running apache).
So, I still disagree.
