154 // This is where feature definitions go. Generally speaking,
155 // turning this stuff off makes things a bit smaller (and less
159 // If you enabled one or more of the shells, you may select which one
160 // should be run when sh is invoked:

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

179 // lots and lots memory for more important things. NOTE: If you enable this
180 // feature, you _must_ have patched the kernel to include the devps patch that
181 // is included in the busybox/kernel-patches directory. You will also need to
182 // create some device special files in /dev on your embedded system:
