"FS block size" !=  "Disk Buffer Size".  Though 8k might have been the
standard FS block size, it was possible -- and occasionally practiced
-- to do 4k/512 filesystems, or 16k/2k filesystems, or M/N filesystems
where { 4k < M < 16k (maybe 32k), log2(M) == int(log2(M)),
log2(N) == int(log2(N)) and M/N <= 8 }.
