rc.sysinit does not recognize the kernel command line argument 'nousb'.

My solution:  On line 148, which reads:

if [  grep -v "nousb" /proc/cmdline 2>/dev/null ]; then

should not be using the test command '[]'.  It should be using the
expression operator '()'.  The line should be:

if (  grep -v "nousb" /proc/cmdline 2>/dev/null ); then
