>Description:

	An awk script defined in /etc/security uses a non-standard
	variable "$LINE" that's incompatible with nawk.

	I note that mawk seems to support this variable, but it is not
	documented for either mawk or gawk.

>How-To-Repeat:

	Try running /etc/security after installing nawk as /usr/bin/awk.

>Fix:

	apply the following patch:
