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.
