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.
