Title:
  cloud-init does not recognize initramfs provided network config in all
  cases

Status in cloud-init:
  Fix Committed
Status in cloud-init package in Ubuntu:
  Fix Released

Bug description:
  Cloud-init relies on the 'ip=' or 'ip6=' parameter to be present in the
  kernel command line in order to consider /run/net-*.conf files.  Those files
  are written by the initramfs indicating that network is was configured.

  When 'ip=' or 'ip6=' is found on the command line, cloud-init will consider
  that to be "kernel command line provided" network, and renders a network
  configuration like:
    # control-manual ens3
    iface ens3 inet dhcp
        broadcast 10.0.3.255
        dns-nameservers 169.254.169.254
        gateway 10.0.3.1

  The key there being that it is not marked 'auto'.  If cloud-init does
  not recognize this, it will render:
    auto ens3
    iface ens3 inet dhcp

  There are some iscsi-root where initramfs configures networking
  but the ip= parameter is not present.  2 such cases are:
   a.) static config in /etc/iscsi/iscsi.initramfs (copied into the initramfs)
   b.) iBft

  If the devices are marked 'auto', then 'networking.service' takes
  the device down during shutdown.  That causes any filesystem activity
  to hang and block shutdown/reboot.
