This is too simplistic of an answer as it ignores the distinction  
between login/non-login, interactive/non-interactive, and restricted  
shell invocations. See bash(1) for details or a good bash reference  
and/or tutorial. In particular see the "INVOCATION" section of the  
bash man page.

/etc/environment is an X Window System environment variable and is not  
relevant to this discussion.

/etc/bashrc is there for example only and I would argue that Apple  
reading it by default is bad form as it's documented in neither the  
man page nor the bash manual. (http://www.faqs.org/docs/bashman/bashref.html#SEC_Top 
) Plus its being included by /etc/profile violates the separation  
between interactive and non-interactive shells. Looks like I need to  
file a bug.
