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.
QEMU/KVM scripts for a CachyOS KDE test VM (run.sh/run.ps1, get-iso,
guest SSH setup), host helper scripts to drive and inspect the
cachyos-gamescope-boot wizard in the guest, and a Claude Code skill
documenting the test workflow.
