System: NetBSD seduction.immanent.net 2.0_BETA NetBSD 2.0_BETA (SEDUCTION) #4: Fri Jun 25 22:14:46 CDT 2004 fredb@seduction.immanent.net:/p/i386--netbsd2/obj/usr/src/sys/arch/i386/compile/SEDUCTION i386

>Description:
	
	Impatient kernel hackers would like to be able to build kernels using
	build.sh without running "config" and "make depend". The "make depend"
	part takes an especially long time, and it often happens that you've
	changed one source file in a way that you know that "make depend" isn't
	needed. It is always possible, of course, to build kernels directly in
	the build directory using the correct "nbmake-<MACHINE>", but it's
	inconvenient to type the tediously long path.
>How-To-Repeat:
	
>Fix:
	
	In the patch below, I'm lumping the "config" and "depend" together,
	even though "config" by itself isn't the burden, partly because "-M"
	is already taken. This is most useful when used with "-u". Perhaps it
	should imply "-u"? (It won't work at all with a clean build.)
