[NTG-context] Set luatex cache directory path

Peter Münster once asked:

What should I do please, to prevent ConTeXt from creating $HOME/luatex-cache?

I'd like to do the same: $ cd $HOME $ ls luatex-cache ls: cannot access 'luatex-cache': No such file or directory $ context test.tex $ ls luatex-cache/ context $ rm -rf luatex-cache $ export TEXMFCACHE=/tmp $ context test.tex mtxrun | unknown script 'mtx-context.lua' or 'mtx-mtx-context.lua' $ export TEXMFCACHE= $ context --version ... mtx-context | current version: 2021.03.31 18:04 What environment variable must change to set the luatex-cache directory? Thank you!
