UBUNTU: SAUCE: add option to hand off all kernel parameters to init
BugLink: http://bugs.launchpad.net/bugs/586386
Some init packages such as upstart find having all of the kernel parameters
passed in useful. Currently they have to open up /proc/cmdline and
reparse that to obtain this information. Add a kernel configuration
option to enable passing of all options.
Note, enabling this option will reduce the chances that a fallback from
/sbin/init to /bin/bash or /bin/sh will succeed. Though it should be
noted that there are commonly unknown options present which would already
break this fallback. init=/bin/foo provides explicit control over options
which is unaffected by this change.
