  [ Balint Reczey ]
  * Merge to Ubuntu from Debian unstable
    - Dropped changes:
      * core: set /run size to 10%, like initramfs-tools does.
        This is now upstream's default, also setting other limits
      * UBUNTU-resolved-disable-global-LLMNR-and-MulticastDNS.patch
      * Lock swap blockdevice while calling mkswap
      * Cherry-pick reversion of detecting WSL by the presence of "microsoft"
        in osrelease
      * journald: stream pid change newline fix
      * network: Change IgnoreCarrierLoss default to value of
        ConfigureWithoutCarrier.
      * network: do not re-attach sd-event object
      * network: attach sd-event in link_load() when creating link dhcp_client
        or ipv4ll
  * debian/rules: Configure LLMNR and MulticastDNS to be disabled by default
    instead of using a carried patch, like before.

  * dhclient-enter-hooks.d/resolved: drop in favor of exit hooks shipped elsewhere.
    isc-dhcp / ifupdown now ship the hooks themselves to push DNS data to
    resolved. Thus enter hook no longer required. (LP: #1890609)

systemd (246-2) unstable; urgency=medium

  * Upload to unstable

systemd (246-1) experimental; urgency=medium

  * New upstream version 246
  * Rebase patches
  * Update symbols file for libsystemd0
  * Bump libapparmor-dev Build-Depends to (>= 2.13)
  * Disable libfido2 support.
    This is only used by homed which we don't enable.

Title:
  improved resolved configuration

Status in systemd package in Ubuntu:
  Fix Released

Bug description:
  improved resolved configuration

  * isc-dhcp-client pushes DNS data to resolved via a hook it ships
  * ifupdown pushes DNS data to resolved via a hook it ships
  * resolvconf skips pulling DNS data that is pushed to resolved
  * systemd doesn't have enter hook anymore

  This way with or without resolvconf, resolved has all the information
  it needs and /etc/resolv.conf can be static, point at resolvconf
  managed file, or at resolved managed file as desired.

  isc-dhcp 4.4.1-2.1ubuntu7
  ifupdown 0.8.35ubuntu2
  resolvconf 1.82ubuntu1 
  systemd TBD
