GEOM meaning

[Dieter Lange]

Hi,

having looked at quite a few sites now, not just 
<http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/geom.html> I 
still cannot find out what "GEOM" means (wrt disks etc., not geography 
or so).  It probably does not mean "Modular Disk Transformation 
Framework". I am not talking of its use and/or definitions, just the 
meaning of the abbreviation or word...

Thanks+kind regards from the only person on the WWW who doesn't know...
