It isn't new. The first cylinder is reserved for the boot blocks.

(On many platform, the first cylinder is reserved for boot blocks.
That's how it is on my vax and hppa computers.)

(It won't need all the cylinder but anyway, the FFS format doesn't
like not starting or ending on cylinder boundary.)

I don't know if its mandatory or prefered limit. Did you try using
the "b" command to disklabel to remove the default limits?

And not to point to the obious, this is the message printed at
startup by disklabel in built-in editor mode (-E):

	Reserving the first data cylinder for boot blocks.
	You can use the 'b' command to change this.
