Isn't there only one cache file? It depends upon which fonts are  
installed. On one machine I have fonts which you will not find in  
ports (or for free at all, I think... they are very old and I got them  
in a commercial package). I don't think this is an option.

Yes.

Did you test f10 on 7.x? I would say f8+ is not supported on 7.1 or  
less, for 7.2 I don't know the current status. Fallback: run fc-cache  
manually (we can not support everything, f4 until 7.x is EOL and f10  
for 8.x is already a lot).

This would at least be a working solution, and not counting the amount  
of work involved it is also the right solution. I think this is  
something for after 8.0.

Bye,
Alexander.
