Move nixos/tests/grub.nix to nixos/tests/grub/basic.nix unchanged, and add new GRUB boot tests under nixos/tests/grub/: - hashed-password: GRUB user authentication with a users.<name>.hashedPasswordFile (a grub-mkpasswd-pbkdf2 hash). The hash is generated in a derivation and passed by store path (via toString) rather than read at evaluation time, to avoid import-from-derivation. Kept separate from basic so each login is exercised on its own VM boot rather than multiplexed onto one menu. - efi: boot through GRUB's EFI support. - graphical: verify GRUB renders its menu in graphical (gfxterm) mode. A marker string is baked into the splash image (which GRUB only draws in gfxterm) and read back via OCR, so a silent fallback to text mode would fail the test rather than pass it. - mirrored-boots: verify GRUB is installed and configured on every path in boot.loader.grub.mirroredBoots.
