Topic: Unit file of apache2.service changed on disk

Apache/2.4.10 (Raspbian)

Anyone know what's changed recently with regard to apache2? This only started happening recently:

After a fresh install of Raspbian Jessie Lite (2016-05-27), I install apache2:

root@raspberrypi:~# apt-get install apache2

At this point, 'service apache2 restart' executes with no warning.

root@raspberrypi:~# service apache2 restart
root@raspberrypi:~#

Following a reboot, however, I get a warning:

Last login: Wed Sep 21 14:31:14 2016 from gigabyte
root@raspberrypi:~# service apache2 restart
Warning: Unit file of apache2.service changed on disk, 'systemctl daemon-reload' recommended.
root@raspberrypi:~#

Following the recommendation eliminates the warning:

root@raspberrypi:~# systemctl daemon-reload
root@raspberrypi:~# service apache2 restart
root@raspberrypi:~#

After a reboot, however, the problem is back. No changes are being made anywhere.

I saw also the Q on reddit https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=160476

Best to post your Q at the dev list: http://httpd.apache.org/lists.html#http-dev There are Apache Debian/Jessie maintainers around.

This is a message of systemd, not Apache. Either apache2.service file really changes (gets rewritten by something?), or (more likely) it's a bug of systemd. As long as Apache starts successfully and it is not mission critical I would ignore this message.
