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