[tex-live] luaotfload on MAC OSX

[Herbert Voss]

Hello all,

I have MacTeX 2017 on Sierra installed and:

bash-3.2$ ls -la /usr/local/texlive/
total 0
drwxr-xr-x   5 voss  wheel  170 25 Mai 09:16 .
drwxr-xr-x  19 voss  wheel  646 25 Mai 08:15 ..
drwxr-xr-x  20 voss  wheel  680 29 Apr 12:28 2016
drwxr-xr-x  20 voss  wheel  680  8 Jun 07:22 2017
drwxrwxr-x  24 voss  1000   816  8 Jun 07:23 texmf-local


When running

luaotfload --update --force -vvv

all TeXLive directories are scanned for fonts: 2017 _and_ 2016

How can I prevent the scanning of all main dirs except of the
current one of 2017 without deleting the old 2016?
