As soon as one applet wants to call another, busybox forks and re-execs
itself. This behaviour can also be enabled for shell commands, but this
is disabled in our config.
If /proc is not mounted and the path is set to /proc/self/exe, the
command will fail. The first command we execute is busybox --install -s,
which IIRC re-execs itself to run the 'ln' applet.
