OK, looking at the settings you've listed, I think these are the kinds of 
things that site.conf was invented for - stuff that is specific not to the 
builds you are doing but to the host machine / site. You can simply put these 
settings in a file called site.conf next to local.conf and they'll be read from 
there; for new build directories you can just copy it in or symlink it from 
some common location.

Cheers,
Paul
