Install Tailscale on LibreELEC

1. SSH Into LibreElec
2. cd into the /storage directory and download the latest release of tailscale from the URL that corresponds with your CPU architecture https://pkgs.tailscale.com/stable/#static

cd /storage && wget https://pkgs.tailscale.com/stable/tailscale_1.84.0_arm64.tgz

3. Extract the file (optionally remove the tar to save space and keep the directory cleaner)

tar xzvf ailscale_1.84.0_arm64.tgz \
rm tailscale_1.84.0_arm64.tgz # optional

4. Create a file called autostart.sh in the /storage/.config directory and make it executable.

nano /storage/.config/autostart.sh && chmod +x /storage/.config/autostart.sh

Add the following contents:

(
cd /storage/tailscale_1.84.0_arm64 &&
./tailscaled --state=tailscaled.state
) &
