Comment (by arg):

 I worked with oddshocks on this a little bit yesterday, and wanted to
 capture my understanding of the situation here.  The current process for
 uploading Fedora AMIs is to write a _filesystem_ to an EBS volume (this is
 according to a conversation with dgilmore last night).  While the new
 pvgrub works with both unpartitioned and partitioned devices, the required
 grub.conf differs between these scenarios.  Our current kickstart (
 https://git.fedorahosted.org/cgit/spin-kickstarts.git/tree/fedora-cloud-
 base.ks ) specifically writes "root (hd0)" in grub.conf, which will only
 work will a volume containing a filesystem.  If the volume contains a
 partitioned disk image, this must be "root (hd0,0)" instead.

 Since the "why" of this issue mentions GPT partitions and possibly
 separating /boot, I suspect that we want to change the F21 kickstart to
 use "root (hd0,0)" and start uploading full disk images as part of this.
