Select this only if you plan to use busybox on full-blown
desktop machine with common Linux distro, not on an embedded box.

+ other encodings will be mainly of historic interest.

As a size optimization, busybox normally exits without explicitly
freeing dynamically allocated memory or closing files. This saves
The file has to be owned by user root, group root and has to be
writeable only by root:
