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!
