`iso/build-iso.sh --offline` (and the workflow's new `offline` box, on by default) adds ~420 MB to the ISO and copies it to /opt/kiosk-offline: - apt/: local repository with every package install.sh's provisioning and the CUPS addon install ask for, NodeSource's nodejs, and all dependencies a fresh server install doesn't already have. Resolved against the source ISO's own package manifest via a synthesized dpkg status (iso/offline/fake-dpkg-status.py), so apt downloads only what's missing and makes the same virtual/alternative choices as the target. - npm/: prebuilt kiosk-app (Electron 42, binary included - it no longer downloads at npm install time) and Web UI node_modules. On first boot, kiosk-firstboot installs online as before when there's internet; with none it waits KIOSK_OFFLINE_WAIT (90s), then runs `kiosk-offline-apt on` (apt.conf.d drop-in: bundle is the ONLY source) and turns it off again afterwards. install.sh notices offline mode via offline_mode_active (lib/config.sh) and installs nodejs from the bundle and unpacks prebuilt node_modules instead of npm install. Package lists moved into PROVISION_APT_PACKAGES / PROVISION_INTEL_APT_PACKAGES / CUPS_APT_PACKAGES so the bundler reads the same lists install.sh installs from. Tested: built against the 26.04.1 ISO, then in a network-less chroot of the ISO's own server filesystem installed every package set, ran provision_create_kiosk_user/install_nodejs/install_app and webui_install_app_files in offline mode (Electron runs, no missing libraries, chrome-sandbox setuid), and ran kiosk-firstboot through the offline switch with a stub install.sh.

|
|
# only there on ISOs built with --offline. kiosk-firstboot turns this on
|
|
# by itself when first boot finds no internet, and back off afterwards.
|
|
# By hand it's for installing things later with no internet - e.g. the
|
|
# CUPS addon: `sudo kiosk-offline-apt on`, ./install.sh -> Addons -> CUPS,
|
|
# then `sudo kiosk-offline-apt off`. While it's on, install.sh also
|
|
# unpacks the bundle's prebuilt node_modules instead of running npm
|
|
# (lib/config.sh's offline_mode_active checks for the file this writes).
|
|
#
|
|
# "Only" matters: with the normal archive still listed, apt would pick
|
|
# newer versions from it that it then can't download.
