When doing a migration, try to guess at a smaller minimum size for the initial filesystem so that systems with giant drives are not needlessly penalized. Start with an even smaller initial filesystem size (16M). Move debug time counters into the main .o file to avoid compiler insanity when turning debug on and off.
