Description Warren Block 2002-03-24 21:10:00 UTC
Section 19.4.10 of the Handbook (2nd Edition) skips over the use of
mergemaster.  It details steps to use instead of mergemaster, but
mergemaster instructions are not included.


Add a "Using mergemaster" title and mergemaster instructions before existing
instructions in 19.4.10, and show a mergemaster command line and usage
De-emphasize the manual merging method section, or at least break it from
the mergemaster section with a title.
How-To-Repeat: See section 19.4.10.

I have already written 3 paragraphs for this pr, and will submit 
a patch for review in a day or so.  Thanks for pointing this out.

         if you would prefer to do that.  We strongly recommend you

+        it with various system configuration files.  Those files are then compared
+        to the ones currently installed in your system.  At this point, files that
+        differ will be shown in &man.diff.1; format, with the <option>+</option> sign

+        and at this point you will have the option of either deleting the new file (referred
+        to as the temporary file), install the temporary file in its unmodified state,
+        merge the temporary file with the currently installed file, or view the

+        reason to change the current file.  You can get help at any time by
+        typing <option>?</option> at the mergemaster prompt.  If the user should
+        choose to skip a file, it will be presented again after all other files
+        have been worked with.</para>

+        current file with the new one.  For most unmodified files, this is the best
+        option.</para>
+      <para>Choosing to merge the file will present you with a text editor,
+        and the contents of both files.  You can now merge them by
+        reviewing both files side by side on the screen, and choosing parts from
+        both to create a finished product.  When the files are compared side by side,
+        the <option>l</option> key will select the left contents and the
+        <option>r</option> key will select contents from your right.
+        The final output will be a file consisting of both parts, which can then be
+        installed.  This is usual option for files where settings have been
+        modified by the user.</para>
+      <para>Choosing to view the diff results again, will show you the file differences
+        just like &man.mergemaster.8; did before prompting you for an option.</para>
+      <para>After &mergemaster.8; is complete with the system files you will be prompted
+        for other options.  &man.mergemaster.8; will ask if you want to rebuild the
+        password file, run <filename>MAKEDEV</filename> and finishing up with a
+        removal of the left over temporary files.</para>
+      <para>If you wish to do the update manually, however,
         you cannot just copy over the files from
 	<filename>/usr/src/etc</filename> to <filename>/etc</filename> and
 	have it work.  Some of these files must be <quote>installed</quote>
