Subject: [PATCH] chore(gitea-runner): fix tty1 autologin on Alpine LXC
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Port the working autologin block from openbao/install.sh so both Proxmox
installers behave identically. The previous version assumed agetty was
already installed and relied on a sed pattern that no-ops on fresh Alpine
images; it also never told PID 1 to re-read /etc/inittab, so the change
required a reboot.

- Install agetty (with util-linux fallback) via apk.
- Drop any existing tty1 line and append the autologin line (robust
  against inittab layout drift across Alpine releases).
- SIGHUP PID 1 and kill any stale getty so init respawns the new line
  immediately — no reboot needed, no first-login "type exit once" wart.
