Thanks a lot.  That put me on the right track.  I see that this file is
mentioned on the wiki, but I hadn't recognized its importance.

I have found and edited texmfcnf.lua, and made progress.

I tried to avoid that, and thanks to your pointer above, won't need that.

However, I'm still not completely happy:  I've set TEXMFCACHE to contain
/var/opt/texlive first and then also an individual directory under $HOME.
When I run context under my personal account, it only uses the second.
I assume that's because I may not write under the first.  There's a comment
in texmfcnf.lua about that.

Does it perhaps make no sense at all to have a system-wide luatex-cache?

Thank you,
Rainer
