init-live.sh: $CMDLINE variable should be provided to switch_root
to let user specify runlevel on grub command line.
Feeding with -c /dev/console as well as busybox switch_root enables that option.

I once sent out a patch to remove the '-c /dev/console' because this is
busybox specific.
What if util-linux gets installed in the initramfs?
Could you please state what the benefit is with this option? Maybe in
the comment?
The disadvantage is obvious, because if you have util-linux in
initramfs, the 'switch_root' command doesn't support that option, and
the 'switch_root' command would always fail.
