I agree. But, AFAIK, that is what the current CVS is for. This based on
observation of the numerous revision/test/revise... procedures I had
observed in the past. If my understanding is correct, then I think that
your next paragraph's "...as it should improve upon LFS 4.0 (leading to a
better 4.1) instead of..." should be considered as a new role for the
"current" CVS. Having a branch that receives closer scrutiny, leading
always to near-term improvements, and one that is a "community sandbox",
leading (through "experimentation") to *long-term* benefits, seems like it
would provide substantial benefit.

Not if they continue to treat the current "CVS" as the sandbox.
Unfortunately, it would then contain both needed "stable" adjustments for
4.0 users and "experimental" adjustments. This would force 4.0 users to
"filter" when they tried to use the CVS version to make needed
My point, if not obvious, is that reassignment of the role of "CVS" to one
like you suggest, and addition of an "unstable" branch pays benefit to the
community, as you envision.

Only if they do not view the current CVS role as appropriate for this sort
of stuff (and I think they shouldn't).

For this to be reasonable, it must be known that there are several
"aggressive" users of the unstable branch that will really "stomp" on
things. Possibly even a "semi-formal" regression-test scenario (I don't
think I like this thought) would be needed to assure that all the patches
added with "no more than a casual glance" really are evaluated. Otherwise,
there is a risk some "time bomb" might migrate from unstable to stable.
Right *now*, we seem to have a cadre of "aggressive" users. Will that be

I think "That's what the current CVS version should be for" if its now

Thereby stepping into the mainstream usage.
