>Description:

If one uses the -s flag to makefs and specifies a size that is not 
evenly divisible by the blocksize, makefs is guaranteed to fail.

From checking out the source I found this happens because: 
  fsopts->minsize = fsopts->maxsize = arg to -s
and in the last steps of ffs_validate():
 - make sure size is at least minsize 
 - round up to the next block 
 - check that size is not greater then maxsize 

I'm not sure if this behaviour should be considered a bug.
At the least, the error message ("size of xxx greater than maxsize") 
is misleading in this case.
