FFE: two small new features in networkd and machinectl

[Martin Pitt]

systemd 225 was released upstream yesterday:
  http://lists.freedesktop.org/archives/systemd-devel/2015-August/034036.html

This includes two small new features and the usual lot of bug fixes:

        * machinectl gained a new verb 'shell' which opens a fresh shell on the
          target machine. It is similar to 'login', but spawns the shell
          directly. The pseudo machine '.host' now refers to the local host and
          is used by default. Hence, 'machinectl shell' can be used as
          replacement for 'su' which spawns the session as a fresh systemd
          unit.

        * systemd-networkd learned to cope with private-zone DHCP options and
          allows other programs to query the values.

The package works fine on wily, I'm doing (mostly) daily builds from upstream, running them through our autopkgtests, and test 225 on my wily laptop.

Note that we don't use networkd anywhere yet, and machinectl is now in a separate systemd-container binary package which we don't install by default any more (it was split out in 224-2).

I would like to ask for a FFE so that we can update to 225 instead of cherry-picking fixes.

Impact seems sensibly limited, go ahead.

This bug was fixed in the package systemd - 225-1ubuntu1

---------------
systemd (225-1ubuntu1) wily; urgency=medium

  * Merge with Debian unstable (FFE: LP: #1489702). Remaining Ubuntu changes:
    - Hack to support system-image read-only /etc, and modify files in
      /etc/writable/ instead.
    - Keep our much simpler udev maintainer scripts (all platforms must
      support udev, no debconf).
    - initramfs init-bottom: If LVM is installed, settle udev,
      otherwise we get missing LV symlinks. Workaround for LP #1185394.
    - Add debian/udev.lvm2.init: Dummy SysV init script to satisfy insserv
      dependencies to "lvm2" which is handled with udev rules in Ubuntu.
    - Add debian/udev.lvm2.service to avoid running the dummy lvm2 init
      script.
    - Provide shutdown fallback for upstart. (LP: #1370329)
    - debian/extra/ifup@.service: Additionally run for "auto" class. We don't
      really support "allow-hotplug" in Ubuntu at the moment, so we need to
      deal with "auto" devices appearing after "/etc/init.d/networking start"
      already ran. (LP: #1374521)
    - ifup@.service: Drop dependency on networking.service (i. e.
      /etc/init.d/networking), and merely ensure that /run/network exists.
      This avoids unnecessary dependencies/waiting during boot and dependency
      cycles if hooks wait for other interfaces to come up (like ifenslave
      with bonding interfaces). (LP: #1414544)
    - Add Get-RTC-is-in-local-time-setting-from-etc-default-rc.patch: In
      Ubuntu we currently keep the setting whether the RTC is in local or UTC
      time in /etc/default/rcS "UTC=yes|no", instead of /etc/adjtime.
      (LP: #1377258)
    - Put session scopes into all cgroup controllers. This makes unprivileged
      user LXC containers work under systemd. (LP: #1346734)
    - systemctl: Don't forward telinit u to upstart. This works around
      upstart's Restart() always reexec'ing /sbin/init on Restart(), even if
      that changes to point to systemd during the upgrade. This avoids running
      systemd during a dist-upgrade. (LP: #1430479)
    - Drop hwdb-update dependency from udev-trigger.service, which got
      introduced in v219-stable. This causes udev and plymouth to start too
      late and isn't really needed in Ubuntu yet as we don't support stateless
      systems yet and handle hwdb.bin updates through dpkg triggers. This can
      be dropped again with initramfs-tools 0.117.
    - Lower Breaks: to plymouth version which has the udev inotify fix in
      Ubuntu.
    - Change systemd-sysv's conflicts to upstart-sysv. (LP: #1422681)
    - Don't build new systemd-journal-remote package and drop
      libmicrohttpd-dev. This is blocked by the MIR (LP #1488341) and feature
      freeze.

    Upgrade fixes, keep until 16.04 LTS release:
    - systemd Conflicts/Replaces/Provides systemd-services.
    - Remove obsolete systemd-logind upstart job.
    - Clean up obsolete /etc/udev/rules.d/README.
    - systemd.postinst: Migrate mountall specific fstab options to standard
      util-linux "nofail" option.
