Here's the scenario:
 
I install the OS and after the installation I install and configure various services. It takes me a long time to do this because I have to manually configure quite a few files as well as create quite a few as well.
 
Things either get screwed up or I decide for various reasons to start with a fresh OS install. I don't want to have to configure all those services from scratch, however. I have also set aside all the new configuration files I created in the process of setting my system up. I've also created a log of all the files I modified which I didn't have to create because they were created for me as part of the original install.
 
All the changes I'm interested in I call my delta. The delta includes the activation of services, creation of files and modification of files. I'm looking for a delta manager that will allow me to apply my specific changes of an OS installation to another OS installation given that my specific changes apply to the target OS.
 
I hear talk about something called an FFS snapshot slated for FreeBSD 5.0-Current but I'm not sure it will do what I describe above. I've read about DIFF and it's a great tool but it leaves too much to be programmed around it for it to functionally satisfy my needs. I submitted this question to the Webadmin list because I think it would be natural for Webadmin to incorporate such a tool since it is already managing most of the information that would be required to make the tool very useful. I wasn't sure if the Webadmin folks consider this in their domain of functionality so I thought I would submit it here as well. Thanks in advance for the enlightenment.
