VM_BOOTLOADER=limine|systemd-boot|grub, VM_STEAMIFY (steamify-install runs after the headless installer, like Calamares does), VM_CACHE (host pacman cache shared as 9p, default ~/vms/pkg-cache). run.sh --headless / VM_HEADLESS=1: no window. Fixes found on the way: the live script deadlocked on is-system-running (it is the running kernel-command-line.service) and now waits for pacman-init; the post script kept forcing the Plasma login over Steamify's gaming-mode SDDM, gave systemd-boot no timeout/default (it waited in the menu for ever), and left ufw blocking the host's ssh; the first-boot check wanted plasmashell in gaming mode.
