I have resolved the issue, so I’m posting this for other users. (The Easy Installer script may need an update.)

Description of Issue
Installing RoonBridge on Fedora 23 using the Easy Installer doesn’t work because roonbridge.service fails to start…
× roonbridge.service - RoonBridge

The error occurs because SELinux prevents the system service from running. I assume this happens because the script and binaries are outside /usr/local/bin.
My solution was to move the installation from /opt/RoonBridge to /usr/local/bin/RoonBridge and edit /etc/systemd/system/roonbridge.service, changing the following line:
# ExecStart=/opt/RoonBridge/start.sh
ExecStart=/usr/local/bin/RoonBridge/start.sh
Finally, execute sudo systemctl daemon-reload and sudo systemctl restart roonbridge.service.
Edit: A simpler solution is to execute:
sudo restorecon -rv /opt/RoonBridge
