I haven't experienced this with F16, F17 or so far F18. What I'm seeing is:

If you have *both* installed, grub2 will want to nuke grub every time an
update shows up, IIRC.
Yum and rpm refuse to install packages which are obsoleted by an
installed package, so you can't really have both. Unless you first
install grub2 and then grub with 'rpm --nodeps'...
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. :)
My comment was simply on the "if you have both" part: it's not really
possible to have both without playing dirty tricks, so even the "if" is
pretty moot.
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
Yes, I think we're both trying to say the same thing: there's no point
having 'grub' in the repositories as its not installable or usable in
practise. The same goes for bunch of other obsoleted packages as well.
