I'm a real outsider here, and don't care much about whether the code
works under 2.4 or not.

But at least one way of interpreting is:

	Code in the 2.6 kernel tree gets updated.  Code in the 2.4
	tree doesn't, you'll have to fetch it from CVS yourself.  You
	need at least 2.4.26; anything lower than that is ancient and
	we're not interested in supporting it.

In other words, the whole text about "ancient kernels" can easily be
interpreted to mean anything *before 2.4.26*, and that 2.4.26 and on
is still fair game to ask the mailing list at the moment.  

It also says that in the *future*, 2.4 will be completely put into
maintenance mode.  If that future is now, IMHO somebody should update
that web page to say so.

With the way that page currently reads, I don't think being curt with
someone who asks about 2.4.26 and pointing them at the web page is
really fair.

[Personally, I don't think you should move to that future just yet;
2-6 more months would be where I would do it.  Where I work, there was
some resistance to moving to 2.6 because it isn't yet "mature" in the
embedded space, as in the major embedded suppliers like MontaVista
aren't really shipping 2.6 yet.  That was a couple of months ago, and
I haven't been paying attentiion; they might be there now.  At any
rate, I recognize my opinion doesn't really matter because I'm not an
active developer; I'm only suggesting what I think is a way to create
less friction in this community.]

Thanks for listening; If I cause more heat than light with this, I
appologize profusely.
