Ok, that said:

This will do what rc.d/webfsd does with conf.d/webfsd:
webfsd.service ---------------------------------------------------------
[Unit]
Description=webfsd
Documentation=man:webfsd(1)
After=network.target

[Service]
ExecStart=/usr/bin/webfsd -p 8080 -u nobody -R /srv/http -f index.html -F

[Install]
WantedBy=multi-user.target


But I think an EnvironmentFile is useful for this service as it only takes
config on the command line.
webfsd at .service --------------------------------------------------------
[Unit]
Description=webfsd
Documentation=man:webfsd(1)
After=network.target

[Service]
EnvironmentFile=/etc/webfs/%i.conf
ExecStart=/usr/bin/webfsd $WEBFSD_ARGS -F

[Install]
WantedBy=multi-user.target
