Title:
  configure_networking uses features not available in initramfs.

Status in initramfs-tools package in Ubuntu:
  Confirmed

Bug description:
  initramfs-tools 0.131ubuntu10 modified configure_networking to use
  run_dhclient instead of ipconfig. configure_networking now fails to
  configure networking in the initramfs because it now uses features not
  available in the initramfs.

  https://git.launchpad.net/ubuntu/+source/initramfs-
  tools/commit/?id=a77729e9a69ff7af4911285c771d80e01b7addfe

  run_dhclient calls dhclient which calls /sbin/dhclient-script.

  /sbin/dhclient-script calls 'chown --reference=$resolv_conf
  $new_resolv_conf', but chown isn't available in initramfs
  /boot/initrd.img-4.18.0-7-generic.

  /sbin/dhclient-script also calls 'chmod --reference=$resolv_conf
  $new_resolv_conf' but busybox chmod in the initramfs does not support
  the option --reference.
