This costs code size for the call to xmalloc. + - Put them on stack. For some very small machines with limited stack + space, this can be deadly. For most folks, this works just fine. + - Put them in 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. config CONFIG_FEATURE_BUFFERS_USE_MALLOC bool "Allocate with Malloc" @@ -26,37 +33,52 @@ config CONFIG_FEATURE_VERBOSE_USAGE bool "Show verbose applet usage messages" default n help - Please submit a patch to add help text for this item. + All BusyBox applets will show more verbose help messages when + busybox is invoked with --help. This will add lots of text to the + busybox binary. In the default configuration, this will add about + 13k, but it can add much more depending on your configuration. config CONFIG_FEATURE_INSTALLER bool "Support --install [-s] to install applet links at runtime" default n help - Please submit a patch to add help text for this item. + Enable 'busybox --install [-s]' support. This will allow you to use + busybox at runtime to create hard links or symlinks for all the + applets that are compiled into busybox. This feature requires the + /proc filesystem. config CONFIG_LOCALE_SUPPORT bool "Enable locale support (system needs locale for this to work)" default n help - Please submit a patch to add help text for this item. + Enable this if your system has locale support, and you would like + busybox to support locale settings. config CONFIG_FEATURE_DEVFS bool "Support for devfs" default n help - Please submit a patch to add help text for this item. + Enable if you want BusyBox to work with devfs. config CONFIG_FEATURE_DEVPTS bool "Use the devpts filesystem for Unix98 PTYs" default y if CONFIG_FEATURE_DEVFS help - Please submit a patch to add help text for this item. + Enable if you want BusyBox to use Unix98 PTY support. If enabled, + busybox will use /dev/ptmx for the master side of the pseudoterminal + and /dev/pts/<number> for the slave side. Otherwise, BSD style + /dev/ttyp<number> will be used. To use this option, you should have + devpts or devfs mounted. config CONFIG_FEATURE_CLEAN_UP bool "Clean up all memory before exiting (usually not needed)" default n help - Please submit a patch to add help text for this item. + As a size optimization, busybox by default does not cleanup memory + that is dynamically allocated or close files before exiting. This + saves space and is usually not needed since the OS will clean up for + us. Don't enable this unless you have a really good reason to clean + things up manually. config CONFIG_FEATURE_SUID bool "Support for SUID/SGID handling" |
