[Why] After search in code, 'kernel_custom_params' is the field which allow user add custom kernel param in job.yaml, not 'kernel_append_root'.

[Reference] - src/scheduler/kernel_params.cr ``` private def kernel_custom_params return @hash["kernel_custom_params"] if @hash["kernel_custom_params"]? end

private def set_kernel_params kernel_params_values = "#{kernel_common_params()} #{kernel_custom_params()} #{self.kernel_append_root} #{kernel_console()}" kernel_params_values = kernel_params_values.split(" ").map(&.strip()).reject!(&.empty?) @hash["kernel_params"] = JSON.parse(kernel_params_values.to_json) @hash["ipxe_kernel_params"] = JSON.parse(initrds_basename.to_json) end ```
