Comment # 11 on bug 1035062 from Patrick Schaaf

For the benefit of others currently stuck with the issue - I'm using the
following systemd unit as a workaround.

Write the unit file to some unique name, e.g.
/etc/systemd/system/workaround-named.service, and then "systemctl
daemon-reload" and "systemctl enable workaround-named" as usual for real
systemd services.

For services other than named, simply modify the "After=" line.

[Unit]
Description=Named Start Workaround
Requires=multi-user.target named.service
After=named.service
Before=multi-user.target

[Service]
Type=oneshot
ExecStart=/bin/true

[Install]
WantedBy=multi-user.target
