  I can accept that custom applications might be easier to include
in images.  Creating a RPM or install script for a rarely installed
program may not make the top of the priority list.  However, if it is
installed identically on multiple systems, it could be converted to rpm
or a scripted install, which could be included in an automated clean
install.  As an example, I uuencode my current DHCP configuration, DNS
files, firewall rules and openvpn certificates into a kickstart file to
cleanly install my firewalls.  Each is different but is scripted, partly
in the scripts that create my kickstart files and partly in the
kickstart post section.
