Init arguments cannot contain spaces
It does not seem possible to send a single argument through
init_args that contains spaces.
Even with something like
init_args="\"hello world\"", which sets
$KOPT_init_args to the literal string
"hello world", when this gets interpolated into
exec /bin/busybox switch_root $sysroot $chart_init "$KOPT_init" $KOPT_init_args
it ends up being sent to the program as two arguments,
This prevents doing something like
/bin/sh -c "touch /foo && exec /sbin/init".
