* merged lp:~mvo/unattended-upgrades/minimal-steps-upgrade
  - This allows performaing the upgrades in minimal chunks so
    that they can be interrupted (relatively) quickly with
    SIGUSR1
  - This feature is not enabled by default yet, in order
    to use it, uncomment the line in 50unattended-upgrades:
     Unattended-Upgrades::MinimalSteps "true";
  LP: #729214
