Description of problem:

Hi!

I use etckeeper to manage my /etc files with git. I was using CentOS 7 with yum and yum-cron before, and yum-cron would auto-commit changes to /etc files after updates. 

I have a Fedora 24 machine with dnf-automatic to essentially get the same automatic update behavior. dnf-automatic does not seem to load dnf plugins like etckeeper, hence changes to /etc due to updated packages are not automatically committed.

Version-Release number of selected component (if applicable):

[root@router ~]# dnf --version

How reproducible:

Every time dnf-automatic updates packages that cause changes to files in /etc or new files in /etc.

Steps to Reproduce:
1. dnf install etckeeper dnf-automatic
   (Installs etckeeper, etckeeper-dnf, dnf-automatic)

2. cd /etc && etckeeper init && etckeeper commit baseline

3. Verify that etckeeper's dnf integration works by running e.g.:
   dnf install -y radvd
   etckeeper vcs log -1

   Should print:

   commit 3cd6be4a98bab8e708d93cc8c18c51656ea2722b
   Author: root <root@machine>
   Date:   Thu Sep 1 13:32:36 2016 +0200

       committing changes in /etc after yum run

       Package changes:
       +0:radvd-2.11-4.fc24.x86_64
   
3. sed -i 's/apply_updates = no/apply_update = yes/' /etc/dnf/automatic.conf

4. systemctl enable dnf-automatic.timer && systemctl start dnf-automatic.timer

5. Wait for updates to appear

Actual results:

Changes to /etc are uncommitted.

Expected results:

Changes to /etc should be committed, like as if I would have run dnf update manually.
