David Heinemeier HanssonandClaude Fable 5 0339b13d12 Join the tailnet from a cidata tailscale_authkey (#97)
* Join the tailnet from a cidata tailscale_authkey

A tailscale_authkey file on the autoinstall drive gets the installed
machine onto the tailnet on its own: the tailscale package is bundled in
the offline mirror and installed only when the key is present, the key is
staged root-only at /etc/tailscale/authkey, and a oneshot first-boot unit
runs tailscale up once the network is really there. On success the key is
deleted and the unit disables itself; on failure both survive to retry on
the next boot, so an offline install joins whenever it first gets
connectivity. ufw allows traffic in on tailscale0 via the same
write-the-rule-then-ignore-the-chroot-exit-code dance as the SSH phase.

Bundling rather than fetching at first boot is deliberate: pacman -Sy
tailscale on a fresh machine is a partial upgrade, and pacman -Syu means
an unattended full system upgrade racing the user's first login. The
offline mirror is a coherent snapshot; installing from it keeps the
target consistent and the install offline-capable. See plans/tailscale.md.

* Do not hold boot hostage for the tailnet join

Review caught that the join unit was Type=oneshot wanted by
multi-user.target: target units implicitly gain After= for their Wants=,
so an offline machine's boot -- SDDM included -- stalled for the full
10-minute timeout, and once timed out the join never retried within that
boot. Type=simple counts as started the moment it forks, so boot proceeds
while the join retries in the background for as long as the boot lasts.
Cleanup moves inside the script, sequenced after tailscale up succeeds,
which preserves the retry-across-boots behavior: key and unit survive a
boot with no connectivity, and the key never outlives a successful join.
