[Bug 1793060] Re: configure_networking uses features not available in initramfs.

[Michael Hudson-Doyle]

Well the missing chown is not going to be a problem because there is
only one user in the initramfs (root!). The chmod failing might be a
problem but it seems a bit unlikely.

I think this code can only be executed if two DHCP leases are accepted.
Are you doing both DHCP4 and DHCP6 or something like that? Can you
provide the complete command line and complete output from a failing
boot?

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.

  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.
