Dear Maintainer,

I'm upgrading my systems periodically using:
     DEBIAN_FRONTEND=noninteractive apt-get -y -q -o 
Dpkg::Options::=--force-confold dist-upgrade

The systemd debian package will silently overwrite
/etc/sysctl.d/99-sysctl.conf with a symlink to /etc/sysctl.conf

If a user changes 99-sysctl.conf to a regular file and puts some changes
into that file, these changes will get lost during the upgrade, thus
possibly breaking systems which depend on those changes.

This is dpkg replacing that file with a symlink. I don't see how systemd can change anything about the behaviour of dpkg.
