Ok, then this discussion probably no longer belongs to #302035.

Ok, so I have made a few tests. In principle, gs should be configured
via defoma, ie, /var/lib/defoma/gs.d/dirs/fonts/Fontmap. However,
/usr/share/gs-gpl/8.01/lib/Fontmap.GS is loaded before that, and any
configuration made there cannot be overwritten later on. IMO this is a
bug in the gs packages, they should not provide any Fontmap at all and
use only defoma for this. I shall report that.

Anyway, for gs-gpl 8.01 one can change this in /etc/gs-gpl/Fontmap.
Simply comment out the line that loads Fontmap.GS. Next I enabled the
attached tex-lw35.hints file via

# defoma-font register-all tex-lw35.hints

This file registers the original URW fonts as provided by tetex-extra
under their PostScript names. Since the gsfonts package registers these
 only as aliases, the 'real' fonts are prefered. So now, eg, Helvetica
is no longer an alias to NimbusSanL, which is still the font provided by
gsfonts, but directly mapped to the NimbusSanL provided by tetex-extra.
So a PS file using NimbusSanL without embedding it will still get the
font from gsfonts. A PS file using Helvetica will get the font from
tetex-extra.

This is interesting as the fonts provided by gsfonts have a few bugs.
See the attached lw35.tex. Processing it with pdflatex gives the
reference, since this uses the fonts from tetex-extra, at least if
pdftexDownloadBase14 is set to 'true'. Processing it with latex & dvips
gives a PS file, where each of the used fonts shows some problems when
viewed using the fonts from gsfonts. With the above mentioned changes
(deactivating Fontmap.GS and registering tex-lw35.hints), the fonts from
tetex-extra are used and the PS file looks fine, too. (It is a good idea
to test this first directly with gs instead of gv, as that prints out
the fonts loaded.)

What do you think? I have *not* yet tested this for any unwanted side
effects. And I am not sure, if it would be a good idea to make something
like this automatically. But providing tex-lw35.hints plus documentation
 (and warnings?) might help some users.
