It might be the example. PLUTO_PEER is related to the peer and peer ID
and thus certificate. The username I think only refers to the IKEv1
XAUTH username, which has no IKEv2 equivalent (yet, until we implement
EAP mschapv2)

Yes, if you check the _updown script you should see all the environment
variables we pass into it from our pluto daemon. Or you can check the
function jam_common_shell_out() in programs/pluto/kernel.c  (we might
have not always updated the _updown env variables comments there)
