Summary:                    switch_root steals args meant for the new init
Description: 
The format for a call to switch_root is:
switch_root [-c /dev/console] NEW_ROOT NEW_INIT [ARGUMENTS_TO_INIT]

The init man page includes:
-z xxx
            The  argument  to  -z is ignored. You can use this to expand
the command line a bit, so that it takes some more space on the stack.
Init can then manipulate the  command  line so that ps(1) shows the
current runlevel.

But, the getopt32() function notices the flag at the end, and bails with a
"switch_root: illegal option -- z"
I'm not a C guru; is there a way to make getopt32() stop parsing at the
first non-option? Or maybe at least exclude the last one?
