f18 yum update breaks grub2 w/ xen

[Mike Wright]

Hi all,

It may be my setup but this is what I found.

Current yum update.

Only breaks xen boots.

Most recent yum upgrade to 3.8.1-201 omits the initramfs line in its 
grub2.cfg file.

After adding these lines it boots.

echo    'Loading initial ramdisk ...'
     module  /initramfs-3.8.1-201.fc18.x86_64.img

My theory is that this is caused if you update xen and install a kernel at 
the same time and it is actually the kernel update calling grubby that 
causes the problem. Does that sound like that might have happened in your 
case?

I think that is the issue too (or, at least, that was what is happening 
on my boxes).

If that is the case, feel free to look at and update with any info you
think is  relevant this bugreport I created:
