The workstation ISO failed to start X with:
(EE) unrecognized option --allow-root
Debian trixie ships Xorg 21.1.x, which removed --allow-root / -allowRoot
entirely — running the X server as root is no longer supported. The live
session now:
- creates a dedicated unprivileged `liveuser` account (in tty, video,
input, audio groups) in build-live.sh;
- starts Xorg as `liveuser` on vt1 (no -allow-root flag at all);
- grants root display access (xhost +SI:localuser:root);
- still runs the installer itself as root, since deploy-disk.sh needs
root. xinit is no longer used (and dropped from the package list).
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).
