This bug was fixed in the package systemd - 229-4ubuntu11

systemd (229-4ubuntu11) xenial; urgency=medium

  * 73-usb-net-by-mac.rules: Split kernel command line import line.
    Reportedly this makes the rule actually work on some platforms. Thanks
    Alp Toker! (LP: #1593379)
  * fsckd: Do not exit on idle timeout if there are still clients connected
    (Closes: #788050, LP: #1547844)
  * libnss-*.prerm: Remove possible [key=value] options from NSS modules as
    well. (LP: #1625584)
  * Backport networkd 231. Compared to 229 this has a lot of fixes, some of
    which we need for good netplan support. Backporting them individually
    would be a lot more work and a lot less robust, and we did not use/support
    networkd in 16.04 so far. Drop the other network related patches as they
    are included in this backport now. (LP: #1627641)
  * debian/tests/networkd: Re-enable the the DHCPv6 tests. The DHCPv6
    behaviour is fixed with the above backport now.
  * pid1: process zero-length notification messages again. Just remove the
    assertion, the "n" value was not used anyway. This fixes a local DoS due
    to unprocessed/unclosed fds which got introduced by the previous fix.
    (LP: #1628687)
  * pid1: Robustify manager_dispatch_notify_fd(). If
    manager_dispatch_notify_fd() fails and returns an error then the handling
    of service notifications will be disabled entirely leading to a
    compromised system. (side issue of LP: #1628687)

Bug description:
  For snappy (at first at least) we need to provide netplan in xenial,
  as for the first snappy GA release we must not use any PPAs any more.

  netplan's NetworkManager backend depends on two patches to read
  configuration and connections from /run/NetworkManager/. These will
  need to be backported for full netplan support; but they are not
  required for snappy as this will use a snapped NM. However, this will
  need a temporary hack
  until snaps can actually properly support OS components like


  netplan: The risk for existing installations is practically zero as nplan 
does not exist in xenial yet and thus will not be pulled in during upgrades.

  NetworkManager: Nothing in xenial expects/uses /run/NetworkManager/
  and as it's an ephemeral tmpfs there is no risk of existing files
  there. If the patches are broken it could in theory happen that
  NetworkManager also does not properly read files from
  /etc/NetworkManager/ any more, so the -proposed package must verify
  that existing connections still work.

  systemd: This does change behavior of networkd quite a bit: RA is now
  being handled in userpsace instead of the kernel, there are some new
  virtual device types, LLDP support, etc., and there are no (known)
  backwards incompatibilities. The 229 version was known buggy with
  DHCPv6 (we disabled these two test cases), and judging by the feedback
  in Debian 231 is now reasonably stable. networkd is not being used by
  default or advertised in Ubuntu 16.04 (so far), so this will not
  affect the vast majority of installations. But while we have quite
  good test coverage, it cannot be ruled out that we break some custom
  setup that uses networkd.

  1. Run "NetworkManager --print-config" and save the output.
  2. Install the proposed NetworkManager and confirm that existing connections 
(from /etc/NetworkManager/system-connections) still work.
  3. Run "NetworkManager --print-config" again and verify that the output is 
the same as in step 1.
  4. netplan has a very comprehensive integration test suite run as 
autopkgtest, which covers NetworkManager (including the /run patches) and 
network. Confirm that it succeeds.
