Ok - Notice that there isn't anything stopping people from using a -rc
version (and there shouldn't be) - E.G.

http://www.kernel.org/pub/linux/kernel/v2.6/testing/linux-2.6.35-rc3.tar.bz2

Thanks.

Ok, that makes sense.

 Thomas> Isn't this what I'm doing already ?

No, you were doing:

+# Compilation
+$(LINUX26_DIR)/.stamp_compiled: $(LINUX26_DIR)/.stamp_configured
+	@$(call MESSAGE,"Compiling kernel")
+	$(MAKE) $(LINUX26_MAKE_FLAGS) -C $(@D)
+ifeq ($(BR2_LINUX_KERNEL_UIMAGE),y)
+	$(MAKE) $(LINUX26_MAKE_FLAGS) -C $(@D) uImage
+endif
+	$(Q)touch $@

E.G. just make (followed by make uImage if uImage is selected).

I guess we should do:

make <format>
if modules:
   make modules
   make modules-install
