Hi,

You have exactly the same problem with fonts and fc-cache.
The current idiom (which works very well) is :

- fc-cache call in fontconfig postinstall scriptlet

- conditional fc-cache in font packages

postinstall scriptlet (using /bin/sh):
if [ -x /usr/bin/fc-cache ]; then
  /usr/bin/fc-cache /usr/share/fonts
fi

postuninstall scriptlet (using /bin/sh):
if [ "$1" = "0" ]; then
  if [ -x /usr/bin/fc-cache ]; then
    /usr/bin/fc-cache /usr/share/fonts
  fi
fi

This works well, catches 100% of the cases, does not force fontconfig
dep in font packages (apps that need the fonts but use another font
rendering tech are happy), does not sprinkle triggers everywhere where
they're difficult to get rid of.

This model should be followed by every package needing optional indexing
provided by another packager IMHO

Regards,
