Almost all the 'wastage' is space for inodes.
You can half it by using FFSv1 (not FFSv2).
A lot of the code has been changed to use unsigned ints for sector
numbers - so you get to 2^32 sectors.
Note that FFSv2 still limits you to 2^32 (or maybe 2^31) inodes.
Also I can't help feeling that the very large number of 'cylinder groups'
isn't actually a very good idea...
FFSv1 limits you to 2^32 (maybe 2^31) fragments - ie >2^32 sectors.
