Adding the 2 above will give you both. Adding both will not result
in any harm. But *do* remove the quotes from the value; as they
aren't required/desired (in this case).
issuing sysctl kern.geom.label.gptid.enable=1
will return
kern.geom.label.gptid.enable=0 -> 1
if it was previously UNet (0)
Same applies to kern.geom.label.gpt.enable
Simply issuing
sysctl kern.geom.label.gpt.enable
will return it's *current* value.
Same applies to kern.geom.label.gptid.enable, or any other
setting.
