Title:
  mkinitramfs fails on Raspian 9 "Stretch"

Status in initramfs-tools package in Ubuntu:
  Incomplete

Bug description:
  Atempting to install kdump-tools fails due to error in mkinitramfs:

  /usr/sbin/mkinitramfs -v -d /var/lib/kdump/initramfs-tools -o
  /var/lib/kdump/initrd.img-4.14.30-v7+.new -4.14.30-v7+

  mkinitramfs: failed to determine device for /
  mkinitramfs: workaround is MODULES=most, check:
  grep -r MODULES /etc/initramfs-tools/

  Error please report bug on initramfs-tools
  Include the output of 'mount' and 'cat /proc/mounts'

  From traces .... it seems it's getting tripped up because the root
  device specified in /proc/cmdline is in the form:
  root=PARTUUID=6ddc62b3-02

  I changed the boot command line to read: root=/dev/mmcblk0p2

  and kdump-tools installed correctly.

  Attaching output of /proc/mounts and mount for good measure.
