- Alternate configuration commands are:
	"make config"      Plain text interface.
	"make menuconfig"  Text based color menus, radiolists & dialogs.
	"make xconfig"     X windows (Qt) based configuration tool.
	"make gconfig"     X windows (Gtk) based configuration tool.
	"make oldconfig"   Default all questions based on the contents of
			   your existing ./.config file and asking about
			   new config symbols.
	"make silentoldconfig"
			   Like above, but avoids cluttering the screen
			   with questions already answered.
	"make defconfig"   Create a ./.config file by using the default
			   symbol values from arch/$ARCH/defconfig.
	"make allyesconfig"
			   Create a ./.config file by setting symbol
			   values to 'y' as much as possible.
	"make allmodconfig"
			   Create a ./.config file by setting symbol
			   values to 'm' as much as possible.
	"make allnoconfig" Create a ./.config file by setting symbol
			   values to 'n' as much as possible.
	"make randconfig"  Create a ./.config file by setting symbol
			   values to random values.

   The allyesconfig/allmodconfig/allnoconfig/randconfig variants can
   also use the environment variable KCONFIG_ALLCONFIG to specify a
   filename that contains config options that the user requires to be
   set to a specific value.  If KCONFIG_ALLCONFIG=filename is not used,
   "make *config" checks for a file named "all{yes/mod/no/random}.config"
   for symbol values that are to be forced.  If this file is not found,
   it checks for a file named "all.config" to contain forced values.
   
	NOTES on "make config":
	- having unnecessary drivers will make the kernel bigger, and can
	  under some circumstances lead to problems: probing for a
	  nonexistent controller card may confuse your other controllers
	- compiling the kernel with "Processor type" set higher than 386
	  will result in a kernel that does NOT work on a 386.  The
	  kernel will detect this on bootup, and give up.
	- A kernel with math-emulation compiled in will still use the
	  coprocessor if one is present: the math emulation will just
	  never get used in that case.  The kernel will be slightly larger,
	  but will work on different machines regardless of whether they
	  have a math coprocessor or not. 
	- the "kernel hacking" configuration details usually result in a
	  bigger or slower kernel (or both), and can even make the kernel
	  less stable by configuring some routines to actively try to
	  break bad code to find kernel problems (kmalloc()).  Thus you
	  should probably answer 'n' to the questions for
          "development", "experimental", or "debugging" features.

A voir si "make defconfig" part du .config présent
et répond au choix non fait avec la config par
défaut.

make oldconfig

Oui je ferai donc ça à chaque fois...J'aurai préféré qu'une option permette : prise en compte du .config, choix automatique des options nouvelles par défaut.

yes | make oldconfig
