Author: dougb Date: Fri Jan 9 11:21:25 2009 New Revision: 186938 URL: http://svn.freebsd.org/changeset/base/186938 Log: MFC the changes from r179725, documentation of the AUTO_UPGRADE knob, and 186677:186749: o Removal of 184781, 184804, and 184832 (automatic installation of files that differ only by VCS Id) o Fix cross-platform builds o Various improvements to the mtree (-U) feature o Remove the last of the MAKEDEV stuff o Switch to using the top level (e.g., /usr/src) Makefile, and specify that we should use the *.mk files from the source directory instead of the installed versions. o Check for the deprecated 'nodev' option in /etc/fstab o Add support for the IGNORE_FILES variable o Before installing a file check to make sure that the target does not already exist as a directory o Check to be sure that the file installed and error out if not o We only need to check for the presence of the target of $PAGER if that variable is actually set Modified: stable/6/usr.sbin/mergemaster/ (props changed) stable/6/usr.sbin/mergemaster/mergemaster.8 stable/6/usr.sbin/mergemaster/mergemaster.sh Modified: stable/6/usr.sbin/mergemaster/mergemaster.8 ============================================================================== --- stable/6/usr.sbin/mergemaster/mergemaster.8 Fri Jan 9 11:20:51 2009 (r186937) +++ stable/6/usr.sbin/mergemaster/mergemaster.8 Fri Jan 9 11:21:25 2009 (r186938) @@ -1,4 +1,4 @@ -.\" Copyright (c) 1998-2003 Douglas Barton +.\" Copyright (c) 1998-2009 Douglas Barton .\" All rights reserved. .\" .\" Redistribution and use in source and binary forms, with or without @@ -24,7 +24,7 @@ .\" .\" $FreeBSD$ .\" -.Dd February 4, 2006 +.Dd January 2, 2009 .Dt MERGEMASTER 8 .Os .Sh NAME @@ -32,14 +32,14 @@ .Nd merge configuration files, et al during an upgrade .Sh SYNOPSIS .Nm -.Op Fl scrvahipCPU +.Op Fl achiprsvCPU +.Op Fl A Ar Target architecture +.Op Fl D Ar /destdir/path .Op Fl m Ar /path/to/sources .Op Fl t Ar /path/to/temp/root .Op Fl d .Op Fl u Ar N .Op Fl w Ar N -.Op Fl A Ar architecture -.Op Fl D Ar /path .Sh DESCRIPTION The .Nm @@ -54,7 +54,7 @@ recommended that you back up your directory before beginning this process. .Pp The script uses -.Pa /usr/src/etc/Makefile +.Pa /usr/src/Makefile to build a temporary root environment from .Pa / down, populating that environment with the various @@ -218,6 +218,14 @@ Specify the path to the directory where .Xr make 1 .
