Matthew Miller 91a9117bc4 switch order of serial and virtual console so logs output to serial console
because that's more useful in openstack. Note does not affect pvgrub
(and therefore ec2)

# This is a basic Fedora 20 spin designed to work in OpenStack and other
# private cloud environments. It's configured with cloud-init so it will
# take advantage of ec2-compatible metadata services for provisioning ssh
# keys. Cloud-init creates a user account named "fedora" with passwordless
# sudo access. The root password is empty and locked by default.
#
# Note that unlike the standard F20 install, this image has /tmp on disk
# rather than in tmpfs, since memory is usually at a premium.
#
# This kickstart file is designed to be used with appliance-creator and
# may need slight modification for use with actual anaconda or other tools.
# We intend to target anaconda-in-a-vm style image building for F20.
