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 hooks.
For systemd init, 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/.
