Do you mean: size /unix?  I rarely see a unix *image* less than 2.5 Mb.  Of
course, it all depends what you're running and how you tune.  For example,
one the system I use every day, the buffer cache alone is 2.5 Mb.  But my
process load is extremely memory intensive: gnu emacs, X window, LaTeX, etc.

I find that 3-4 Mb is typical.  As an aside, I find that it's not very easy to
determine the exact image of unix.  Anyone have any good ideas on that?
