iso/build-iso.sh remasters the official 26.04.x live-server ISO (downloaded and checksum-verified, or --iso PATH) with xorriso, replaying its BIOS/UEFI boot records unchanged. It adds: - /autoinstall.yaml: Subiquity autoinstall that answers locale/keyboard/SSH and by default leaves only network, storage and identity interactive (--username/--auto-storage/--auto-network/--no-confirm/--fully-automatic make those automatic too). late-commands copy the repo (a clone of the current HEAD) to /opt/ubuntu-based-kiosk and enable a first-boot service. - iso/firstboot/kiosk-firstboot(.service): on first boot, takes tty1, waits for cloud-init and internet, copies the repo to the admin user's home and runs ./install.sh as that user with temporary passwordless sudo (removed on every exit path). Failed/interrupted installs re-run next boot. install.sh hooks for this: - KIOSK_UNATTENDED=1 makes ask_yes_no take each prompt's default and skips the Core Settings menu (--unattended). - KIOSK_PROVISION_DONE_MARKER is touched by provision_finish before the reboot prompt, so the caller can tell a finished install from an interrupted one.

# Installed by the custom ISO (iso/build-iso.sh) and enabled from its
|
|
# autoinstall late-commands. Runs install.sh once, on tty1, the first
|
|
# time the freshly installed system boots - takes tty1 over from getty
|
|
# so an interactive install has a keyboard and screen, then hands tty1
|
|
# back. /var/lib/kiosk-firstboot/pending is removed once the install
|
|
# finishes, so this is a no-op on every boot after that; an interrupted
|
|
# or failed install leaves it in place and simply runs again next boot.
