>Description:
	Create a ffs file system with 64k blocks, 8k frags. See how the kernel
	reads the 1st alternate super block instead of the super block.
	The 1st alternate is at block 128 which is also the super block
	address for UFS2.

	These userland utilities might be affected (grep SBLOCKSEARCH ...):
