Increases the size and complexity of a minimal kernel to include another file system not necessarily needed otherwise. b. Uses a standard file system. Which standard? c. Makes FreeBSD (installation) dependant on MicroSoft. d. Allows everyone with a dos floppy (or without) to modify/destroy the O/S. On the down side of things, one has to ask: 1. What does it exactly buy? * A smaller boot image? No * A simpler boot? No. The SysV bfs has SOME merit. Except that it is very slow for some reason. The (only) advantage is in a simplified & unified boot. The files are contigious, in a very simple directory. All this is nullified when one considers that it is an option. So the 2nd, 3rd stage boot still need to know multiple file system formats. Note: The above (my portion) is only worth $0.02 or less :-) Simon
