Author: jhb Date: Fri Jul 13 13:23:48 2012 New Revision: 238423 URL: http://svn.freebsd.org/changeset/base/238423 Log: The etcupdate utility is a tool for managing updates to files that are not updated as part of `make installworld' such as files in /etc. It manages updates by doing a three-way merge of changes made to these files against the local versions. It is also designed to minimize the amount of user intervention with the goal of simplifying upgrades for clusters of machines. The primary difference from mergemaster is that etcupdate requires less manual work. The primary difference from etcmerge is that etcupdate updates files in-place similar to mergemaster rather than building a separate /etc tree.
