The minix shell (adds just 30k) is quite complete and handles things
like for/do/done, case/esac and all the things you expect a Bourne
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 staticly linked version of busybox
+ 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 this will *also* cause applets to take precedence
+ over shell builtins of the same name. So turning this on will
+ eliminate any performance gained by turning on the builtin "echo"
+ and "test" commands in ash.

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.
