147// This is where feature definitions go.  Generally speaking,
148// turning this stuff off makes things a bit smaller (and less 
149// pretty/useful).

159// BusyBox will, by default, malloc space for its buffers.  This costs code
160// size for the call to xmalloc.  You can use the following feature to have
161// them put on the stack.  For some very small machines with limited stack
162// space, this can be deadly.  For most folks, this works just fine...
163//#define BB_FEATURE_BUFFERS_GO_ON_STACK
164// The third alternative for buffer allocation is to use BSS.  This works
165// beautifully for computers with a real MMU (and OS support), but wastes
166// runtime RAM for uCLinux.  This behavior was the only one available for
167// BusyBox versions 0.48 and earlier.

173// feature, you _must_ have patched the kernel to include the devps patch that
174// is included in the busybox/kernel-patches directory.  You will also need to
175// create some device special files in /dev on your embedded system:
176//        mknod /dev/mtab c 10 22
