I'm sure lots of people will disagree on this one, but here's a list of
everything I removed from my 3B1.  DANGER * DANGER * DANGER : I don't
suggest this for the inexperienced or weak-of-heart.  Don't even THINK
about removing all these UNLESS you know what they are and are sure YOU
don't need them.  For me, I haven't missed them at all in the last two years.
I run my own very simple windowing system (wlogin) on the console and 
do system administration the old, user-hostile, manual way.

ONE MORE TIME: you'd better be pretty damn sure you know what you're doing
before tying this!  Basically, I just did a rm -rf on the following:

Before getting too excited, I think this was pretty drastic surgery, but
it only freed up a little over 1MB on my disk....

Get and thoroughly read the book UNIX SYSTEM SECURITY by Wood and Kochan,
Hayden Books, 1985, ISBN 0-8104-6267-2.  It's filled with good suggestions
and (for the most part) is directly applicable to the 3B1, assuming you've
gotten rid of the UA....

Underneath its cosmetic shell, the 3B1 is just another System V Unix box.
Within those limitations, there's no reason it shouldn't be possible.
