From f33e1d9fa20381afa3be7e7f560c59845bfa5cec Mon Sep 17 00:00:00 2001 From: Amos Waterland Date: Fri, 14 Dec 2007 11:30:22 -0800 Subject: [IPV4]: Updates to nfsroot documentation The difference between ip=off and ip=::::::off has been a cause of much confusion. Document how each behaves, and do not contradict ourselves by saying that "off" is the default when in fact "any" is the default and is descibed as being so lower in the file.
