Now that Fedora 7 is out I figured it was time to update the EC2 instance howto. It is almost exactly the same as creating a FC6 instance so if you want to know the details you can reference that article.

Here is an updated script for creating the AMI the only change between this and the one for FC6 is the yum repo and the image name:

[code lang=”bash”]
#!/bin/sh

dd if=/dev/zero of=fedora7-i386.img bs=1M count=1 seek=1024
/sbin/mke2fs -F -j fedora7-i386.img

mount -o loop fedora7-i386.img /mnt

mkdir /mnt/dev
mkdir /mnt/proc
mkdir /mnt/etc
for i in console null zero ; do /sbin/MAKEDEV -d /mnt/dev -x $i ; done

cat < /mnt/etc/fstab
