Hello,

On arm64 I have this:-

% uname -KU
1400057 1400057
% man 8 gptzfsboot
No manual entry for gptzfsboot
%

Is gptzfsboot only for certain archs? I only query it because recently zpool offered an 
upgrade and suggested looking at it. I see that man 8 gptzfsboot is available on 
13-stable on amd64.
