It just get ignored.

Yes, indirectly. What it does is that it takes a snapshot of the FcFontSet 
* fonts from the config; via the fc-mmap program, one can pass the -s flag 
to specify if one wants to take a snapshot excluding the user-part of 
the configuration or not. No definitive choice have been made up to now 
by Patrick on how the mmap files should be named or placed on disk, 
depending of their content.

I think answer for #2 holds, but I should check it out. I am writing a 
very similar patch, fixing a few issues I still have... I will post it 
here too. Regards,
