  [ Mauricio Faria de Oliveira ]
  * Prevent race condition that might ignore DHCP OFFERs/ACKs
    when dhclient receives DHCP traffic noise. (LP: #1926139)
    The previous/racy behavior can be switched back on with
    the 'DHCP_FD_FLAGS_POKE=0' environment variable or
    the 'dhcp.fd_flags_poke=0' kernel cmdline option.
    - d/p/lp1926139-watch-socket-fd-later.patch: fix, switches.
    - d/apparmor/sbin.dhclient,usr.sbin.dhcpd: /proc/cmdline r.

    in the initramfs. (LP: #1937110)

  isc-dhcp (4.4.1-2.3ubuntu2.2) jammy; urgency=medium

  * Disable make_resolv_conf() if systemd-resolved is in use (LP: #1972029)
    This functionality was moved from systemd 246-2ubuntu1 (enter-hook) to
    isc-dhcp 4.4.1-2.1ubuntu7 (exit-hook). The part overriding
    make_resolv_conf() was dropped, but is needed to avoid it overriding
    /etc/resolv.conf, managed by sd-resolved (stub-resolv.conf).
