I think you've heard my point already though ;-) So at long last I implemented this. I think it does what you'd expect, now. I put 'glibc, kernel-smp, kernel, kernel-hugemem, kernel-enterprise and kernel-bigmem' in the default exactarchlist. You can also set exactarchlist in your yum.conf under [main] and it will use that list. Right now it, effectively, obsoletes exactarch entirely. Now, something to keep in mind, things this will NOT let happen: foo.x86_64 will not be updated by foo.i386 on an x86_64 the biarch 'trees' will be considered separately, that's how it will be and I think that's how it SHOULD be. Having said that a .noarch pkg will get them both :) -sv
