Maybe the supercede is the frequently options which is customised. But I think
I should not ignore the customised dhcp configuration /etc/dhclient.conf instead of
using the default dhcp configuration in dracut source directory.
Of course it will be fine to append all of the configuration customised dhclient.conf
to the default configuration by constructing the initram image.
