Title:
  networking stop incorrectly disconnects from (network) root filesystem

Status in MAAS:
  Triaged
Status in ifupdown package in Ubuntu:
  Confirmed
Status in ifupdown source package in Xenial:
  Confirmed

Bug description:
  With the switch to systemd, all support for iscsi root (and other)
  filesystems disappeared, since shutdown yanks the rug out from under
  us.

  Rather than just relying on /etc/iscsi/iscsi.initramfs (which d-i
  creates..), the DEV check should be expanded to include iscsi devices,
  and networking.service ExecStop should honor those checks.

  Related bugs:
    * bug 1229458: grub2 needed changes
    * bug 1621615: network not configured when ipv6 netbooted into cloud-init
    * bug 1621507: ipv6 network boot does not work

  [Impact]

  With the changes from the above, the iscsi root (at least in the ipv6
  case) gets disconneceted prior to clean shutdown (ifdown downs the
  interface), resulting in a failure to enlist, commission, or deploy
  cleanly under MAAS. (and a failure to cleanly unmount the root
  filesystem when it is over iscsi.)

  [Test Case]

  Given a MAAS 2.0 installation, and the packages in the other bugs,
  attempt to enlist, commission, or deploy a host with xenial.

  [Regression potential]

  This restores the pre-xenial behavior of not shutting down the
  interface if there are network drives at the time that neworking is
  stopped (making it a no-op.)  The additional change is to detect
  "/dev/disk/by-path/*-iscsi-*" as a network disk, replacing the check
  for the existence of /etc/iscsi/iscsi.initramfs, which was only
  created by debian-installer (and maas until recently).
