[NTG-context] OSFONTDIR in ConTeXt Standalone

Dear list, ConTeXt Standalone in Windows uses the system font directory out of the box. In Linux, one needs to set OSFONTDIR to "/usr/share/fonts//". Since this is the default directory for fonts in Linux, wouldn’t it be possible to set it by default in ConTeXt Standalone for Linux? Many thanks for your help, Pablo -- http://www.ousia.tk
