adjust "ExecStart=/usr/sbin/named -4 -f -u named -t /var/named/chroot"
to match your path and most likely remove the "-t" (chroot) option
unless you provide ExecStartPre stuff is stripped out by purpose

a simple systemd unit looks like below

 -f Run the server in the foreground (i.e. do not daemonize)

foreground is needed for "Type=simple" so that the process don't fork -
no need to do so unless you have services strictly ordered after
named.service

[Unit]
Description=DNS Server

[Service]
Type=simple
ExecStart=/path/your-binary

[Install]
WantedBy=multi-user.target
