But, it's not just if both installed, is it? The grub2 package obsoletes
grub, and yum follows obsoletes by default in dependency resolution.

Panu, you would know this better than I, so clearly I'm going crazy
somewhere. If you could explain how, I'd appreciate it. :)

Here's on an F17 image booted in a cloud service (so no grub at all
installed initially):

  $ rpm -qa |grep grub
  grubby-8.11-1.fc17.x86_64

(As expected, just grubby; nothing else matches.)

  $ sudo yum install grub
  [...]
  Package grub is obsoleted by grub2, trying to install
  1:grub2-2.0-0.39.fc17.x86_64 instead
  Resolving Dependencies
  --> Running transaction check
  ---> Package grub2.x86_64 1:2.0-0.39.fc17 will be installed
  --> Processing Dependency: grub2-tools = 1:2.0-0.39.fc17 for package:
  --> 1:grub2-2.0-0.39.fc17.x86_64
  [...and so on]

Even "yum install grub-0.97" gets this behavior. Now, I can set
"obsoletes=0" in /etc/yum.conf if I _really_ want to get grub installed, but 

  a) I don't actually want to change the default behavior of yum on the final
     image 

  b) I don't want users to get messed up if they innocently change that back
     to its default

  c) I'm not even sure how I would go about changing that pre-transaction in
     appliance-creator and other tools
