Political discussion about the GPL often centers around the ``copyleft''
 
requirements of the license.  Indeed, the license was designed primarily
 
to embody this licensing feature.  Most companies adding non-trivial
 
features (beyond mere porting and bug-fixing) to GPL'd software, and
 
thereby implicating these requirements, are already well aware of their
 
more complex obligations under the license.\footnote{There has been much legal

However, in our experience with GPL enforcement, few redistributors'
 
compliance challenges relate directly to the copyleft provisions; this is
 
doubly true for most embedders.  Instead, the distributions of GPL'd
 
systems that we encounter typically consist of a full operating system

We digress for this chapter from our discussion of GPL's exact text to
 
consider the matter of derivative works --- a concept that we must
 
understand fully before considering GPLv2~\S\S2--3\@. GPL, and Free
 
Software licensing in general, relies critically on the concept of
 
``derivative work'' since software that is ``independent,'' (i.e., not
