You overmixed them ;)

gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada0

(lowercase 'i' and pmbr, 1-sector pre-loader for -b)

Dmitry:

I should have read UPDATING AGAIN before even posting my problem and doing things from memory ;-)

But after from a current 10-stable ISO.

gpart bootcode -p /boot/gptzfsboot -i 1 ad0
gpart bootcode -p /boot/gptzfsboot -i 1 ad1

Still yields my original issue
