pdftex.cfg
From ConTeXt wiki
There's no more pdftex.cfg since TDS 2004!
pdfTeX's config file lives in texmf/pdftex/config/.
If you don't use LaTeX, you need not to load any font maps with the pdftex.cfg; ConTeXt can load the needed map files at runtime:
# map psfonts.map
If you use only a few fonts, you can load the needed font maps in pdftex.cfg and comment out the appropriate entries in cont-sys.tex:
map psfonts.map map +texnansi-bh-lucida.map
