Partitions are needed for mainly two reasons.  The most important reason
is that it allows the use of grub.  This makes any image created with
this tool bootable and it looks and feels like any bare metal system.
It also allows for the ability of creating multiple partitions so an
appliance can have a septate data partition(s).  This allows for
flexibility in your update/data model, where if you want to, you can
switch out your "appliance engine" and keep the data intact.

The ability for a tool to create these partitioned disk images via the
command like, livecd-creator, is very helpful in reproducing known state
appliances, epically with the rising use of visualization.  Going
through a actual install in a vm limits you to VM container, xen, kvm,
vmware and adds extra overhead of building on a machine with extra virt
resources.  We have also noticed that an image that was installed via
anaconda is larger that an image created with the appliance creator tools.
