+	This hook enables tailscale service within initramfs.
+
+	It copies all required files and binaries to initramfs and runs the Tailscale agent.
+	Configuration is copied from the host into the initramfs per:
+	
+		* /etc/initcpio/tailscale/tailscaled.state to /var/lib/tailscale/tailscaled.state
+
+		* /etc/initcpio/tailscale/default.env to /etc/default/tailscaled
+
+	It works with both, systemd and busybox init systems; whatever you choose remember to also configure network and a ssh server.
+
+	For systemd inits, see 'sd-network' and 'sd-tinyssh' hooks provided by mkinitcpio-systemd-extras package.
+
+	Run /usr/bin/setup-initcpio-tailscale if you haven't already to initialize the configuration files at /etc/initcpio/tailscale/.
