  [ Michael Biebl ]
  * Bump priority of libnss-systemd to standard
  * logind: avoid shadow lookups when doing userdb client side
  * Disable DNSSEC support by default in resolved.
    The upstream default, DNSSEC=allow-downgrade can lead to compatibility
    issues with certain network access points. Previously, DNSSEC support
    was only turned off when built for a stable Debian release, but it is
    safer and more consistent to just generally change the default to
    DNSSEC=no. (Closes: #959996)
  * Bump debhelper compatibility level to 13.
    Use the debhelper-compat package to declare the compatibility level and
    drop debian/compat.
  * Convert to dh_installsystemd and disable dh_installsystemduser
  * Drop custom initramfs update code.
    Now handled by dh_installinitramfs which is enabled by default in compat
    level 12 and above.

  [ Dan Streetman ]
  * Cherry-pick fix from upstream master to adjust UseGateway= default
    - network: change UseGateway= default to UseRoutes= setting
    - network: honor SetDNSRoutes= even if UseGateway=False
    (LP: #1867375)

  [ Topi Miettinen ]
  * Delete empty lines at end of file.
    Upstream commit hooks don't allow empty lines and of course they serve no
    purpose.

Title:
  40-vm-hotadd.rules attempts to set non-existent sysfs parameters

Status in systemd package in Ubuntu:
  Fix Released
Status in systemd source package in Focal:
  New

Bug description:
  In focal, udev's 40-vm-hotadd.rules (from debian/extra/rules-ubuntu)
  tries to write to invalid (as of 5.4.0-1010-azure) sysfs nodes
  resulting in warnings such as:

  Apr 29 22:36:46 focal01 systemd-udevd[266]: memory7:
  /usr/lib/udev/rules.d/40-vm-hotadd.rules:9 Failed to write
  ATTR{/sys/devices/system/memory/memory7/state}, ignoring: Invalid
  argument

  Perhaps 40-vm-hotadd.rules needs to be updated for 5.4 semantics,
  removed, or something else. This behavior is present on systems
  upgraded from 18.04 (via d-r-u) as well as new focal systems, upon
  first reboot of the VM.

  udev: 245.4-4ubuntu3
