132 // This is where feature definitions go. Generally speaking,
133 // turning this stuff off makes things a bit smaller (and less
137 // BusyBox will, by default, malloc space for its buffers. This costs code
138 // size for the call to xmalloc. You can use the following feature to have
139 // them put on the stack. For some very small machines with limited stack
140 // space, this can be deadly. For most folks, this works just fine...
141 //#define BB_FEATURE_BUFFERS_GO_ON_STACK
143 // Turn this on to use Erik's very cool devps, and devmtab kernel drivers,
144 // thereby eliminating the need for the /proc filesystem and thereby saving
145 // lots and lots memory for more important things. NOTE: If you enable this
146 // feature, you _must_ have patched the kernel to include the devps patch that
147 // is included in the busybox/kernel-patches directory. You will also need to
148 // create some device special files in /dev on your embedded system:
149 // mknod /dev/mtab c 10 22
