I ran into a problem which I couldn't solve with the way updmap
manages the map files. The goal was to install a truetype font,
which is to be included by pdftex without conversion (because
pdf can handle ttf) and must be converted to pk for use in
postscript documents (when dvips is called).

If I put a line like

jvnr8r Verdana " TeXBase1Encoding ReEncodeFont " <8r.enc <jvnr8a.ttf

into my map file (which ends up in psfonts.map and pdftex.map), pdftex
is quite happy with it but dvips doesn't call mktexpk anymore and actually
includes the font in tt format into the postscript file.
If I remove the above line from the map and instead put an equivalent
line in ttfonts.map, mktexpk is called again, but for both pdftex and
dvips, which doesn't really make sense for a pdf document.

Well, the solution would be if I could put the above line only into
pdftex.map and also put the equivalent line into ttfonts.map. Both
isn't currently possible with updmap.
