	       includes directories such as /usr/bin and /usr/local/bin.

	   o   Default paths for some utilities and device nodes.  Examples include such paths as /dev/null (_PATH_DEVNULL), /dev/mem (_PATH_MEM),
	       and /etc/nologin (_PATH_NOLOGIN), among others.

	   o   Paths for some default directories such as /dev (_PATH_DEV) and /tmp (_PATH_TMP) as well as paths for some miscellaneous utilities
	       such as csh(1), /bin/csh (_PATH_CSHELL).
