Now this I really like. It would make benchmarking 8K vs. 16K blocksizes
much easer, as well as of course avoiding the "initdb required after
rebuilding" problem.

BTW, pretty much every BSD system is going to be using 16K block sizes
on large partitions; the cylinder group size and filesystem overhead is
way, way too small when using 8K blocks.
