Found an alternative to this, leaving it here for anyone interested. I
start the slave node with:

start_slave(NodeShortName) ->
    CodePath = code:get_path(),
    {ok, Node} = ct_slave:start(NodeShortName, [{boot_timeout, 10}]),
    true = rpc:call(Node, code, set_path, [CodePath]),
    {ok, Node}.

Hence I do not need to "rebuild" the directories.

Fred, Tristan, thank you for your help I can consider this matter closed.

Best,
r.
