Tha 'ash' shell adds about 60k in the default configuration and is
the most complete and most pedantically correct shell included with
busybox. This shell is actually a derivative of the Debian 'dash'
shell (by Herbert Xu), which was created by porting the 'ash' shell

- Use a command builtin to the shell over one with the same name,
- that may be on the system.
+ This option causes the selected busybox shell to use busybox applets
+ in preference to executables in the PATH whenever possible. For
+ example, entering the command 'ifconfig' into the shell would cause
+ busybox to use the ifconfig busybox applet. Specifying the fully
+ qualified executable name, such as '/sbin/ifconfig' will still
+ execute the /sbin/ifconfig executable on the filesystem. This option
+ is generally used when creating a statically linked version of busybox
+ for use as a rescue shell, in the event that you screw up your system.
+
+ Note that when using this option, the shell will attempt to directly
+ run '/bin/busybox'. If you do not have the busybox binary sitting in
+ that exact location with that exact name, this option will not work at
+ all.
