Not a surprise.... :-)

Well, that isn't necessary......
If you installed mysql, for example, there will be a
/lib/systemd/system/mysqld.service file. When mysql is installed it defaults to
being disabled, as shown in the output of the systemctl command below.
[egreshko at meimei system]$ systemctl status mysqld.service
mysqld.service - MySQL database server
Loaded: loaded (/lib/systemd/system/mysqld.service; disabled)
Active: inactive (dead)
CGroup: name=systemd:/system/mysqld.service
To enable it on boot, just do
systemctl enable mysqld.service

No need to worry about all of that unless you are creating your own services. i.e.
those not installed via rpm from fedora.
