Generally speaking,// turning this stuff off makes things a bit smaller (and less // pretty/useful).////// If you enabled one or more of the shells, you may select which one// should be run when sh is invoked://#define BB_FEATURE_SH_IS_ASH//#define BB_FEATURE_SH_IS_HUSH//#define BB_FEATURE_SH_IS_LASH#define BB_FEATURE_SH_IS_MSH//// BusyBox will, by default, malloc space for its buffers.  This costs code// size for the call to xmalloc.  You can use the following feature to have// them put on the stack.  For some very small machines with limited stack// space, this can be deadly.  For most folks, this works just fine...#define BB_FEATURE_BUFFERS_GO_ON_STACK// The third alternative for buffer allocation is to use BSS.  This works// beautifully for computers with a real MMU (and OS support), but wastes// runtime RAM for uCLinux.  This behavior was the only one available for// BusyBox versions 0.48 and earlier.//#define BB_FEATURE_BUFFERS_GO_IN_BSS//// Turn this on to use Erik's very cool devps, and devmtab kernel drivers,// thereby eliminating the need for the /proc filesystem and thereby saving// lots and lots memory for more important things.  NOTE:  If you enable this// feature, you _must_ have patched the kernel to include the devps patch that// is included in the busybox/kernel-patches directory.  You will also need to// create some device special files in /dev on your embedded system://        mknod /dev/mtab c 10 22//        mknod /dev/ps c 10 21// I emailed Linus and this patch will not be going into the stock kernel.//#define BB_FEATURE_USE_DEVPS_PATCH//// show verbose usage messages//#define BB_FEATURE_VERBOSE_USAGE//// Use termios to manipulate the screen ('more' is prettier with this on)//#define BB_FEATURE_USE_TERMIOS//// calculate terminal & column widths (for more and ls)#define BB_FEATURE_AUTOWIDTH//// show username/groupnames for ls//#define BB_FEATURE_LS_USERNAME//// show file timestamps in ls#define BB_FEATURE_LS_TIMESTAMPS//// enable ls -p and -F#define BB_FEATURE_LS_FILETYPES//// sort the file names//#define BB_FEATURE_LS_SORTFILES//// enable ls -R//#define BB_FEATURE_LS_RECURSIVE//// enable ls -L//#define BB_FEATURE_LS_FOLLOWLINKS//// Disable for a smaller (but less functional) ping//#define BB_FEATURE_FANCY_PING//// Make init use a simplified /etc/inittab file (recommended).#define BB_FEATURE_USE_INITTAB////Enable init being called as /linuxrc//#define BB_FEATURE_LINUXRC////Have init enable core dumping for child processes (for debugging only) //#define BB_FEATURE_INIT_COREDUMPS////Make sure nothing is printed to the console on boot//#define BB_FEATURE_EXTRA_QUIET//// enable syslogd -R remotehost#define BB_FEATURE_REMOTE_LOG//// enable syslogd -C//#define BB_FEATURE_IPC_SYSLOG////Disable for a simple tail implementation (2.34k vs 3k for the full one).//Both provide 'tail -f', but this cuts out -c, -q, -s, and -v. #define BB_FEATURE_FANCY_TAIL//// Enable support for loop devices in mount//#define BB_FEATURE_MOUNT_LOOP//// Enable support for a real /etc/mtab file instead of /proc/mounts//#define BB_FEATURE_MTAB_SUPPORT//// Enable support for mounting remote NFS volumes. // You may need to mount with "-o nolock" if you are// not running a local portmapper daemon...//#define BB_FEATURE_NFSMOUNT//// Enable support forced filesystem unmounting // (i.e., in case of an unreachable NFS system).// #define BB_FEATURE_MOUNT_FORCE//// Enable support for creation of tar files.#define BB_FEATURE_TAR_CREATE//// Enable support for "--exclude" and "-X" for excluding files#define BB_FEATURE_TAR_EXCLUDE//// Enable support for tar -z option (currently only works for inflating)//#define BB_FEATURE_TAR_GZIP //// Enable reverse sort#define BB_FEATURE_SORT_REVERSE//// Enable uniqe sort#define BB_FEATURE_SORT_UNIQUE//// Enable command line editing in the shell.  // Only relevant if a shell is enabled.
