What you have seen is the motivation behind the creation of the BFS
file system. The BFS filesystem allows you to have a root filesystem
of any type without the bootstrap having to know how to read it.
I'm guessing that the boot off of S5 was done with a floppy? I'm
not familiar with the i386 port, just the 3B2. On the 3B2 you can boot
off the /stand (BFS) filesystem or off the floppy (BFS or S5).
Without BFS, you would need to rewrite the bootstrap every time you
added a new filesystem type.
