One of the strongest historical arguments for using *BSD as the base for 
development of an embedded/appliance-style system has been that this is 
precisely what FreeBSD is not: by keeping a useful base set of applications in 
revision control, tested together, and integrated together, we provide an 
excellent starting point for building network appliances, storage appliances, 
ISP systems, etc.  It's when you start having to deal with big piles of 
applications that aren't tested together, managed in a single revision control 
tree, and so on, that maintainability and complexity become problems for these 
users.  I can tell you that if we ripped out BIND, sendmail, and a dozen other 
highly useful base system components out into ports, I would be using another 
system, because it is precisely this integration that makes FreeBSD most 
useful as a starting point :-).  This isn't an argument for endless growth (or 
even significant growth) of the base system, rather, an argument for not 
abandoning integrated revision control and building of the current system.

Sure, we can make the build-time construction of the system modular in a 
cleaner and more comprehensive way, and provide better binary delivery 
mechanisms that offer more of the build-time flexibility we already have to 
the end-user.  But an argument to dismember the current system is a 
non-starter.  If I wanted to try to build a complete and integrated system 
from scratch, without any guarantees that the versions of the components had 
been tested together, without an integrated build system, etc, I could always 
use one of a thousand Linux distributions.  A self-standing buildworld out of 
a single CVS checkout is one of our greatest strengths.

(I realize that you weren't arguing for that end goal exactly, but I want to 
make sure that if we embark on the further modularization approach, we do so 
with an understanding that it needs to be an improvement on what we have, not 
an elimination of one of our most important features!)
