Dash kiosk installer for boxes with an HDMI panel (cage + Chromium on tty1) - #55
Conversation
scripts/kiosk: a cage + Chromium kiosk unit on tty1 that shows the local dash with the owner token, waits for the dash before launching, restarts on failure, and an idempotent installer (apt, unit, getty@tty1 handoff, graphical.target). First target: Vadelma's 1024x600 panel; same script for the VTA. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

…n tty2) The VTA runs Ubuntu 26.04 where apt has only a Chromium shim, and its vta-console.service already owns tty1. The variant installs Chromium from snap, points the wrapper at /snap/bin/chromium, moves vta-console to tty2 with a drop-in, and puts the kiosk on tty1.

If carwatch-chat remains unavailable for all 120 attempts—for example, because startup recovery takes longer than expected—the loop falls through and launches Chromium against the unavailable URL. Cage then remains running, so systemd does not restart the wrapper, defeating the stated purpose of preventing an error page once the dashboard later recovers. Exit after the timeout so Restart=always retries, or continue waiting until the health check succeeds.

…profile Review by codexmb on #55: (1) snap Chromium cannot write a dot-directory in the real home, so the profile now defaults to ~/snap/chromium/common/ carwatch-kiosk when the binary is the snap, and the Ubuntu installer sets the binary through a unit drop-in instead of sed; (2) the launcher exits nonzero after the readiness window instead of starting Chromium against a dead dash, so systemd's Restart keeps retrying. tests/test_kiosk_launcher.py runs the real script with stubbed curl and cage: no browser on a dead dash, tokenized URL on a live one, snap profile path for the snap binary.

The vendor drop-in 40-rpi-volatile-storage.conf makes journald volatile, so the previous boot's log vanishes and an unexplained reboot (Vadelma, 15 Sep 2026 15:03) cannot be diagnosed. Override with Storage=persistent, capped at 200M for the SD card. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

Follow-ups, not in this PR: the token is visible in the process command line on the box (single-user box; a local redirect page would hide it); a landscape layout for the dash at 1024x600 if the phone layout does not fit; Ubuntu boxes (VTA) need Chromium from snap or another browser since apt has no
