我有以下启动配置：

  # Use the GRUB 2 boot loader.
  boot.loader.grub.enable = true;
  boot.loader.grub.useOSProber = true;
  boot.loader.grub.version = 2;
  boot.loader.grub.efiSupport = true;
  boot.loader.grub.efiInstallAsRemovable = true;
  boot.loader.efi.efiSysMountPoint = "/boot/efi";
  # Define on which hard drive you want to install Grub.
  boot.loader.grub.device = "nodev"; # or "nodev" for efi only
  boot.loader.systemd-boot.enable = true;
  #boot.extraModprobeConfig = "options nouveau noaccel=1 runpm=0 nofbaccel=1 modeset=1";
  #boot.kernelPackages = pkgs.linuxPackages_latest;

可能是什么原因导致此问题？什么是“规范”路径？

答案1

我必须将启动分区安装在.../boot而不是/mnt/boot...

答案2

由于 ESP 分区的指定挂载点是/boot/efi：

boot.loader.efi.efiSysMountPoint = "/boot/efi";

它必须安装在下面/mnt，即/mnt/boot/efi在运行时nixos-install（与 相同nixos-rebuild）。该错误failed to get canonical path of '/boot/efi'表明情况并非如此。

一个常见的错误是将 ESP 安装在 中/mnt/boot，您似乎遇到过这个错误。安装 ESP/boot也是错误的方法。
