Attached patch adds an option to allow dist-upgrade in cron job.  Note that:

  - This option detects when a non-stable dist is present in "apt-cache policy",
    and disables the upgrade in that case.  I think it's reasonably safe to do
    automatic dist-upgrades if you're only running stable.

  - My patch adds a big warning saying that this is an experimental feature, to
    ensure noone enables it without knowing the possible implications.

Hello,

As already spot by Michael, "unattended-upgrades" is the most logical
way of supporting it and I don't think it should be done directly by
APT.

Due this concerns and since we hadn't no activity on this bug in more
then a year, I'm closing it.

Please, feel free to reopen it and start a new discussion about it if
you disagree with this.

Thanks in advance,
