From: Chen Qi <qi.c...@windriver.com>
The purpose of this script is to set up commands that busybox provides
if /usr is missing. In this way, the system can still boot into single
user mode for recovery or repair if the /usr partition is broken.
For normal use case, that is, /usr is on the same partition as /, or
/usr is correctly mounted at boot time, this script has no real effect.
