You don't have to define the face manually. But you have to write Elisp
code to find the current values of the attributes of an existing face,
and write those values to a custom-file which can be read back the next
time you start Emacs.
Example: If you execute the following in a Lisp-Interaction buffer:
(describe-face 'default)
you will see all the default face's attributes whose *current* values
you have to save to a file: :family, :width, :height, :slant,
:foreground, :background, etc.
A function to inspect each attribute in turn is called 'face-attribute
So again, for the default face, you can get each value:
(face-attribute 'default :family)
(face-attribute 'default :height)
(face-attribute 'default :background)
And so on. Get the value of each attribute of the face you're
interested in, and then write those values to a file and you can read
them back in at any time.
