+SOFTWARE REQUIREMENTS
+
+   Compiling and running the 2.1.x kernels requires up-to-date
+   versions of various software packages.  Consult
+   ./Documentation/Changes for the minimum version numbers required
+   and how to get updates for these packages.  Beware that using
+   excessively old versions of these packages can cause indirect
+   errors that are very difficult to track down, so don't assume that
+   you can just update packages when obvious problems arise during
+   build or operation.

 CONFIGURING the kernel:
 
  - Do a "make config" to configure the basic kernel.  "make config"
    needs bash to work: it will search for bash in $BASH, /bin/bash and
    /bin/sh (in that order), so hopefully one of those is correct. 
 
+   (Do not skip this step even if you are only upgrading one minor
+   version.  New configuration options are added in each release, and
+   odd problems will turn up if the configuration files are not set up
+   as expected.  If you want to carry your existing configuration to a
+   new version with minimal work, use "make oldconfig", which will
+   only ask you for the answers to new questions.)
+
  - Alternate configuration commands are:
 	"make menuconfig"  Text based color menus, radiolists & dialogs.
 	"make xconfig"     X windows based configuration tool.
+	"make oldconfig"   Default all questions based on the contents of
+			   your existing ./.config file.
