From 2005b07aa88ae556f7268c6c6cbe5513c01d28d7 Mon Sep 17 00:00:00 2001
From: Greg Lehey <grog@FreeBSD.org>

Subject: 1.  Modify config to issue different code for debugging. 2.  Config
 complains if you use -g:

    Debugging is enabled by default, there is no ned to specify the -g option

3.  Config warns you if you don't use -s:

    Building kernel with full debugging symbols.  Do
    "config -s BSD" for historic partial symbolic support.
    To install the debugging kernel, do make install.debug

    (BSD was the name of the config file I used; I print out the same
    name).

4.  Modify Makefile.i386, Makefile.alpha, Makefile.pc98 and config to
    work if a kernel name other than 'kernel' is specified.  This is
    not absolutely necessary, but useful, and it was relatively easy.
    I now have a kernel called /crapshit :-)

5.  Modify Makefile.i386, Makefile.alpha, Makefile.pc98 "clean" target
    to remove both the debug and normal kernel.

6.  Modify all to install the stripped kernel by default and the debug
    kernel if you enter "make install.debug".

7.  Update version number of Makefiles and config.
