Summary

0001425: 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?
