newfs limits? 10TB filesystem max?

Aren't you supposed to use gpt(8) to define partitions
larger than 2 TB?

Then the question is whether newfs reads
gpt-partitioned disks? From newfs(8):

Before running newfs the disk must be labeled using
bsdlabel(8). 

How did you create such a huge partition? Your
question is quite interesting, I'm at a
storage-solution which supports LUN's larger than 2.2
TB.
