The main disadvantage is the increased  memory  footprint  which  you
have  to  pay  for  a  flexibility on the target which is usually not

Your (a) is not really an argument; there are several  solutions  for
this "problem", for example:

	genext2fs - ext2 filesystem generator for embedded systems

	gBootRoot - distribution creation program which may be used by a normal user

(b) is a matter of taste; for embedded systems, I tend  to  prefer  a
fixed,  static  configuration  which  does  not  cost too much of the
resources which may be somewhat limited (espacially ROM and RAM).

By the way, ALL software projects are done by iterative  prototyping.
Some companies call their prototypes "releases", that's all.
