[NTG-context] TeXlive 2020 / Gentoo Linux: ConTeXt does not find itself (sort of)...]

[mylists at posteo.de]

Hi Matthijs,

thanks for your support. My first attempts to change the installation
accordingly failed unfortunately.

( I had tried to change /usr/share/texmf-dist/web2c/texmfcnf.lua  )

What file/place would be the best to adapt these settings?

Cheers!
Meino
