OK, I figured out on my Debian system the equivalent file is
/usr/share/ghostscript/9.54.0/Resource/Init/Fontmap.GS. I think that’s
just for the builtin fonts, and shouldn’t be edited; this is because
your changes could easily be lost the next time the package is upgraded
or reinstalled.

So where is the equivalent to /var/lib/ghostscript/fonts/Fontmap? And
is it automatically generated in turn from config files in /etc
somewhere?
