What is the issue?

The --exit-node flag should accept an IP or a node name.

--exit-node string
        Tailscale exit node (IP or base name) for internet traffic, or empty string to not use an exit node

For the initial tailscale up however, the node name option results in an error:

invalid value "my-exit-node" for --exit-node; must be IP or unique node name

After running the initial tailscale up and authenticating, it behaves as it should (the --exit-node flag accepts node names as well as IPs).

Steps to reproduce

On a device with a fresh Tailscale installation (and no user data):

sudo tailscaled

sudo tailscale up --exit-node my-exit-node
