If BusyBox built-in applets are not enough for our embedded requirement, new tools should be added.
This recipe shows three methods to integrate new utilities to a BusyBox-based embedded system.
In order to extend a fork of BusyBox by adding functionality from an existing utility, just compile and install the new utility as a separate binary, which will be explained later. But to distribute one binary exactly to our embedded system and get a smaller-sized system, integrating new applets into BusyBox is a direct method.
To do so, use the small
sstrip program as an example.
sstrip is a small utility that removes the contents at the end of an ELF file that are not part ...
