Actually ... I don't personally see it as that at all.  We still want to 
minimize changes and i think Alan's comments are correct.

Right, and we may do it, however if we do it, it will be because there 
is a growing market and it has no impact on the i686 distro.

And the act of modifying anaconda in that way DOES go against what 
CentOS main goal is (a perfect rebuild of sources).

That doesn't mean we won't do it ... it just means we need a very good 
reason to do it :D

I also did not read it like that. All those things are NOT changing 
anything in the main distro, but are adding on to it.

But that might be the argument.  For example, we are probably not going 
to add Gnome 2.22 into centos-5 for precisely that reason :D

Right ... so all in all, I though Alan's comments were positive and not 

Either way though, the real issue is that we might provide i586 support 
as an addon feature if it looks like i586 is required for new projects 
.. but the support may be broken at times since upstream does not ensure 
their source compiles with that "--target i586" switch.
