The VMs will not be deployed via ks. The ks role in my case is merely 
to install an OS template that can be used as an "VM image" on 
Openstack; that's what makes it complicated. :-)
This template then will be used to deploy virtual machines; what 
happens is something along the lines of:
- create file for template disk (1GB is enough to accomodate a minimal 
Centos 6):
fallocate -l1G template.img

- install an OS on it using my ks:
virt-install bla bla nux' kickstart

- create a new file for a VM, say 20 GB
fallocate -l20G newvm.img

- now use the template to image the new VM's disk
dd if=templateinstalledbyks.img of=newvm.img

But in doing so the end result will be a / partition and filesystem of 
the template's original size, which is very small (1GB as per above); 
they both need to be expanded to match the new size of 20GB.

Do you understand now?
