Yes you can, you have patches in the source format to patch the source
at build time. Red Hat replaces loads of config files this way.

If it is a GUI application then it will be using gconf or the kde
equiv, which is really easy to set default vaues for.

For instance (the deps are made up, but the argument holds):

My girlfriend wants to install pidgin. pidgin deps on
caching-nameserver that deps on squid. Squid is a system level
package, and my girfriend is asked what port to run the squid proxy
instance. She runs and cries. It has to "just work". If it's not
secure in the default config, then patch the config defaults, and let
the power users use the GUI tools, webmin or just vim to do the
powerful stuff.

What does that string mean? Seriously, if I can't understand it then
my g/f has no hope. Can it be translated into 100 languages? Can it be
qualitified in a finite number of enumerated values?
