OpenBao has a working installer and its own README, but the root README
never linked it. Add a row to Available Scripts (grouped with the other
Proxmox installer, gitea-runner) and extend the Proxmox VE Requirements
line so both LXC scripts are mentioned consistently.
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.
