Can you post an example of some of these packages? Are they as simple as a
list of packges that you pump back into dselect for upgrade or a wrapper
.deb package that you created?

eg. of deselect list
   [Reference machine]
   dpkg --get-selections > required_packages
   [On target machine]
   cat required_packages | dpkg --set-selections
   apt-get dselect-upgrade

Seeing this is in place in CBV, how easy is this to implement?

Maybe someone can post an example of how these are done? Can the /upgrade/
rpm system do anything to help us add/update things between versions of
RedHat?

I raise the second point as I am also concerned about the
upgrade/maintainability aspect. If we develop an installer that uses
someapp-1.2.3-4.rpm or someapp-1.2.34.deb, how much of a hassle will it be
when we move to a new version of the distribution?

We wont need to upgrade often, but it will have to happen someday, and we
have to keep in mind that we will need to repeat what we have done now.

I definitely vote for one / partition + swap on the first drive. If there is
two HD's in a machine, take the second one out for parts!

In rare cases we probably could break off /home, though the extra protection
it gives us is small in comparison to automatic backups, second drives,
server storage etc.

Raul <- Another KISS supporter! :)
