Getting back to the "codebase" question, my preference is "installation 
tree."  It's a concrete reference to the directory tree where Drupal is 
installed.

The term "code base" connotes, in my mind, the original source code at 
the Drupal.org site.  It's a more abstract term, so that one might say 
"CivicSpace is built on the Drupal code base."  See the Wikipedia entry 
(http://en.wikipedia.org/wiki/Codebase) for another example (and no, I 
didn't submit the Wikipedia entry).
