F17 on AWS EC2

[Joseph VLcek]

I am trying to upgrade an AWS EC2 f16 to f17 following these instructions:
http://fedoraproject.org/wiki/Upgrading_Fedora_using_yum#Fedora_16_-.3E_F...

I start with AMI:  ami-0316d86a as listed here:
https://fedoraproject.org/wiki/Cloud_SIG/EC2_Images

The instructions describe:
"Change the following kernel commandline parameter directly in the bootloader menu,
which
is shown during bootup, or edit the line in /etc/grub*.cfg to remove ro and rhgb and
append rw
rd.info rd.convertfs enforcing=0"

However /etc/grub*.cfg is empty:
[root@domU-12-31-39-04-F1-72 etc]# file /etc/grub2.cfg
/etc/grub2.cfg: symbolic link to `../boot/grub2/grub.cfg'
[root@domU-12-31-39-04-F1-72 etc]# file ../boot/grub2/grub.cfg 
../boot/grub2/grub.cfg: empty

Am I doing something wrong?

How can one get a f17 EC2 instance?

Thanks in advance for any help/suggestions.
