Kenneth,

If systemd is proving to be a headache, it can be easily replaced by
sysvinit in Stretch. As root:

apt-get install sysvinit-core
cp /usr/share/sysvinit/inittab /etc/inittab

is all it takes.  systemd libraries are not removed which some apps
require, no special repos are needed, etc.  The init part is just
removed. I've been running Stretch like this for months.  No problems.

Here's the link I used: 

http://without-systemd.org/wiki/index.php/How_to_remove_systemd_from_a_Debian_Stretch_installation

I just did the first Required steps, nothing else.
