(The first version of this change, in commit 39fad29, broke `nix-build -A nixosTests.installer.simpleUefiSystemdBoot`. This is the 2nd version, which hopefully does not break anything.) `nixos-rebuild build-vm-with-bootloader` currently fails with the default NixOS EFI configuration: $ cat >configuration.nix <<EOF { fileSystems."/".device = "/dev/sda1"; boot.loader.systemd-boot.enable = true; boot.loader.efi.canTouchEfiVariables = true; } EOF $ nixos-rebuild build-vm-with-bootloader -I nixos-config=$PWD/configuration.nix -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/nixos-20.09.tar.gz [...] insmod: ERROR: could not insert module /nix/store/1ibmgfr13r8b6xyn4f0wj115819f359c-linux-5.4.83/lib/modules/5.4.83/kernel/fs/efivarfs/efivarfs.ko.xz: No such device mount: /sys/firmware/efi/efivars: mount point does not exist.
