System: NetBSD quark.mobile.fnop.net 3.99.15 NetBSD 3.99.15 (QUARK) #43: Sun Jan 29 03:22:38 WET 2006 rpaulo@quark.mobile.fnop.net:/usr/obj/sys/arch/i386/compile/QUARK i386
Architecture: i386
Machine: i386
>Description:

Some of our drivers/subsystems have prequisistes that config should know
about. config should have a way to specify what requires what and then
automagically include the dependencies or warn the user.

Let's see, for example, the stf problem:
defpseudo stf:          ifnet
file    net/if_stf.c                    stf & inet & inet6      needs-flag

If one builds a kernel with stf but without inet6, the build will
fail becaause stfattach() is automatically included in ioconf.c b
config(1). This is not being idiot-proof. (how may times did you tried
building a kernel without mpacpi/mpbios but with ioapic?)

>How-To-Repeat:

>Fix:

config couuld have the following require directive:

	require stf:	inet & inet6
	require ioapic: mpbios | mpacpi
