prompt "Buffer allocation policy"
default "Allocate with Malloc"
help
- Please submit a patch to add help text for this item.
+ There are 3 ways BusyBox can handle buffer allocations:
+ - Use malloc. 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.

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.
