Updated 2 x86_64 boxes, each has a very complete set of core+extras+others. The 2nd box came up with bind broken. rpm -q said it had the fc5 bind! I manually installed the fc6 (using smart update), and now it's OK. /root/install.log said 'installing bind-9.3.2-4.1.x86_64' and also other related packages. But it didn't actually work!
