# Steamify's own VM tests on GitHub's runners (4 vCPUs, 16 GB, KVM; skipped on the Gitea mirror): the same as
# `scripts/vmtest.sh` in steamify-cachyos-dev, on this commit's steamify.sh. The base is the newest Steamify ISO
# release (steamify-cachyos-live-iso, built and kept on the git.upriser.nl mirror: GitHub releases take at
# most 2 GB per file): 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).
# Needs the secret GIT_UPRISER_URL (the mirror's address, for the ISO). Two VMs at a time, 2 vCPUs each.
