GEOM classes. It works by loading a shared library via dlopen(3) mechanism with class-specific code, it is also responsible for communicating with GEOM via libgeom(3). Per-class shared libraries are going to be stored in /lib/geom/ directory. It provides also few standard commands like 'list', 'load' and 'unload' for existing classes which aren't aware of geom(8). More info will be send on freebsd-current@ mailing list. Supported by: Wheel - Open Technologies - http://www.wheel.pl
