Thanks very much.  This will work, we just need to depend on
mknfonts.tool and populate /usr/share/GNUstep/Fonts at postinst.  There
are a few issues, though:

      * mknfonts.tool hasn't been touched for ages, we need to update it
        for the latest NS*Mask definitions.  This looks trivial.
      * mknfonts doesn't compute traits, etc.  I guess we can live
        without that.
      * For some reason there is some inconsistency between some of the
        names fontconfig knows/shows and those generated by mknfonts
        (specifically, by the FT_Get_Postscript_Name function).  For
        example, with the cairo backend DejaVu is "DejaVu Sans", and
        with the art backend (the property list generated by mknfonts)
        it is "DejaVuSans" (without the space).  So setting the font for
        one backend makes the other backend unable to discover the
        configured font...
      * The trickiest part seems to be how to craft the trigger.  It
        needs to be run after fontconfig's trigger when the fc-cache is
        updated.  I have no idea how to solve this.

One more question, from your initial message:

This means that gnustep-back-common should still depend on defoma and
run the above in its postinst at least until squeeze+1, right?  Is there
a document (wiki page or whatever) describing the Defoma removal goal
distribution-wide?
