Additionally updates the dependencies.
+ "make olddefconfig"
+ Like above, but sets new symbols to their default
+ values without prompting.
+
"make defconfig" Create a ./.config file by using the default
symbol values from either arch/$ARCH/defconfig
or arch/$ARCH/configs/${PLATFORM}_defconfig,
"make randconfig" Create a ./.config file by setting symbol
values to random values.
+ "make localmodconfig" Create a config based on current config and
+ loaded modules (lsmod). Disables any module
+ option that is not needed for the loaded modules.
+
+ To create a localmodconfig for another machine,
+ store the lsmod of that machine into a file
+ and pass it in as a LSMOD parameter.
+
+ target$ lsmod > /tmp/mylsmod
+ target$ scp /tmp/mylsmod host:/tmp
+
+ host$ make LSMOD=/tmp/mylsmod localmodconfig
+
+ The above also works when cross compiling.
+
+ "make localyesconfig" Similar to localmodconfig, except it will convert
+ all module options to built in (=y) options.
+
You can find more information on using the Linux kernel config tools
in Documentation/kbuild/kconfig.txt.
