Title:
  Dependency loop via sockets.target

Status in dbus package in Ubuntu:
  New
Status in dbus source package in Impish:
  New

Bug description:
  basic.target waits for dbus.socket (via sockets.target) AND
  dbus.socket waits for basic.target, too, delaying dbus-daemon startup.
  At some point a timeout happens, dbus is started and all queued
  services try to start registering to the bus at the same time.

  All services registering at the same time, seems to be triggering bugs
  like this more often:

  This happens since Hirsute (dbus 1.12.20-1ubuntu3), where the
  following delta was added:
