What if the MAC address has already been set in the environment?
AFAIR, the MAC address in the environment has a higher precedence
than others.
May be I missed this, but I don't remember any discussion about changing
this assumption.
So, if the assumption is still correct, you shouldn't change the MAC in the env.
