4.3.2 Busybox

Busybox combines many standard Linux distribution programs in one single
program in order to minimize memory requirements of the file system. The
program is only started via symbolic links. Busybox evaluates the name and
can in this way implement different functions in one program.
When compiling Busybox you can choose the programs to be integrated. It is
thus possible to adapt the size of the program to the required functions. The
Linux fieldbus coupler implements all the required functions for a minimum
system.
The following call lists the implemented programs:

during compilation they can be changed arbitrarily (see chapter 5). The list
contains the following programs:

• ifconfig
• hostname
