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).
