export install_path="/mnt/sda1/tailscale"
wget -O- 'https://raw.githubusercontent.com/lanrat/openwrt-tailscale-enabler/main/bin/tailscale-install' | sh

3. Run tailscale for the first time:

/etc/init.d/tailscale start
tailscale up --accept-dns=false--advertise-routes=10.0.0.0/24 --advertise-exit-node

4. Enable tailscale at boot:
