programs by that name. Supplying an empty command path (as above) means
the only commands busybox can find are the built-in ones.
-(Note that the standalone shell currently requires /proc/self/exe to
-launch new applets.)
+Note that the standalone shell requires CONFIG_BUSYBOX_EXEC_PATH
+to be set appropriately, depending on whether or not /proc/self/exe is
+available or not. If you do not have /proc, then point that config option
+to the location of your busybox binary, usually /bin/busybox.
