# Steamify's own test run on the Gitea mirror (git.upriser.nl, its own runner; skipped on GitHub): the same as
# `scripts/vmtest.sh` in steamify-cachyos-dev, on this commit's steamify.sh. The base is the newest Steamify ISO
# release of the mirror (steamify-cachyos-live-iso): the boot loader tests (limine, systemd-boot, grub) install
# it with this commit's Steamify, then the suites (cli, menu, hw, installer, toggles) run on a plain VM from
# the same ISO (its Steamify step skipped: the suites start from a system without Steamify).
# The runner needs /dev/kvm and privileged containers, about 12 GB of RAM for two VMs at a time (6 GB to
# install, 4 GB to test, 2 vCPUs each).
