IJulia kernel - JULIA_LOAD_PATH &| JULIA_DEPOT_PATH ignored/irrelevant -?

Hi guys.

Only have just started looking at Julia and ain’t a programmer and have this, most likely trivial, question.

I set those envs:
export JULIA_LOAD_PATH="/opt/share/julia/extralib:$JULIA_LOAD_PATH"
export JULIA_DEPOT_PATH="/opt/share/julia/extralib:$JULIA_DEPOT_PATH"

I see:

yet! … kernel ends up here:
/root/.local/share/jupyter/kernels/julia-1.7

Why is that - that’s one - and how to fix it - meaning make it land where you want?

many thanks, L.
