Tailscale settings lost on reboot

I found a way to make the /etc/rc.local startup script work for starting Tailscale. Figured I’d add the solution here, just because its much less tedious than logging in and editing /usr/bin/gl_tailscale/ through the terminal.

It seems like there’s a few seconds after startup that are a bit variable where tailscale can’t start if the command is run too early.

Feel free to edit it however it works for you.

Here’s everything in the file:

# Put your custom commands here that should be executed once
# the system init finished. By default this file does nothing.

# Method to restart Tailscale. Sometimes would be running, but non-functional.
start_tailscale()
{
        tailscale status &> /tmp/tailscale.before
        tailscale down
        tailscale up --advertise-exit-node --accept-routes --advertise-routes=xxx.xxx.xxx.0/22 &> /tmp/tailscale.info
        sleep 3 ; tailscale status &> /tmp/tailscale.after
}

. /lib/functions/gl_util.sh
remount_ubifs

# Wait for 30 seconds after startup, then run the Tailscale start method
sleep 30 ; start_tailscale &

exit 0
