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).
