147 // This is where feature definitions go. Generally speaking,

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.
168 //#define BB_FEATURE_BUFFERS_GO_IN_BSS
170 // Turn this on to use Erik's very cool devps, and devmtab kernel drivers,
171 // thereby eliminating the need for the /proc filesystem and thereby saving
172 // lots and lots memory for more important things. NOTE: If you enable this
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:
