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. + +Buffers allocation policy +CONFIG_FEATURE_BUFFERS_USE_MALLOC + 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. + Enable the ar applet CONFIG_AR - ar is an archival utility program used to creates, modify, and + ar is an archival utility program used to create, modify, and extract contents from archives.
