Title:
  Don't stop the upgrade to inform about service restarts

Status in “pam” package in Ubuntu:
  New

Bug description:
  Binary package hint: update-manager

  The pam upgrade blocks the entire release upgrade process until it is
  acknowledged:

  Preparing to replace libpam0g 1.1.0-2ubuntu1 (using .../libpam0g_1.1.1-2ubuntu1_i386.deb) ...                  
  Unpacking replacement libpam0g ...                                                                             
  Setting up libpam0g (1.1.1-2ubuntu1) ...                                                                       
  Checking for services that may need to be restarted...Checking init scripts...                                 

  Restarting services possibly affected by the upgrade:
    saslauthd: stopping...starting...done.             
    cron: stopping...starting...done.                  
    atd: stopping...starting...done.                   

  Services restarted successfully.

  While this is normally a good practice, when upgrading to a new
  release, it risks hanging the upgrade process and serves no purpose
  (there is no option other than go ahead and all services get restarted
  at some point during the upgrade process, so this isn't news).  This
  should be notification should be disabled during upgrades to a new
  release.
