The ISO now boots straight into a GTK installer instead of dropping to a tty. Structure: - installer/arcline-installer: small GTK3 (Python) frontend that drives scripts/deploy-disk.sh — pick a disk, choose boot mode, type the device path to confirm, watch the deploy log, reboot. Pure helper logic is tested against lsblk (lowercase keys, pseudo-devices filtered). - scripts/build-live.sh: builds build/rootfs/<edition>-live by cloning the CLEAN rootfs and layering on live-boot, a minimal X session (Xorg + openbox), the installer, and the deploy tooling under /usr/lib/arcline (deploy-disk.sh + btrfs/init.sh + edition fstabs, laid out so the scripts' own path resolution works unchanged). - overlays/live/: arcline-installer.service + session script that start Xorg on vt1 (with -allow-root) and run the installer as the X client. - build-iso.sh: builds the live rootfs for the squashfs AND stages the clean rootfs archive into isofiles/install/ — the installer deploys the clean archive, so what's installed is the hardened system, never the live session with the installer in it. - Refactor: ARCLINE_LIVE handling removed from build-rootfs.sh and configure-system.sh (now lives entirely in build-live.sh). - validate.sh now checks overlays shell scripts + installer python. - docs updated (building.md, architecture.md, installer/README.md).

# Arcline OS — graphical installer (runs in the live session)
|
|
#
|
|
# A small GTK3 frontend for scripts/deploy-disk.sh. It boots to the console
|
|
# of the live ISO and walks through: pick a target disk -> confirm (type the
|
|
# device path, like scripts/install.sh) -> install, streaming the deploy log
|
|
# into the window. Everything destructive is delegated to deploy-disk.sh,
|
|
# which is shipped in the live image at /usr/lib/arcline.
|
|
#
|
|
# Requires root (the live session runs as root). No network needed.
