assertion (name' == name) failed at ... luksroot.nix:143:186

Trying to install nixos with luks + lvm on a VM, but getting error on 20.09: assertion (name' == name) failed at /nix/var/nix/profiles/per-user/root/channels/nixos/nixos/modules/system/boot/luksroot.nix:143:186 Thinking it's a typo (' to be dropped?)

Steps:

1. Create a blank VM with EFI in Virtualbox and use the Minimal NixOS cd
2. In general, follow these steps: https://gist.github.com/martijnvermaat/76f2e24d0239470dd71050358b4d5134
3. Relevant config snippet:

   boot.loader.systemd-boot.enable = true;
   boot.loader.efi.canTouchEfiVariables = true;
   boot.initrd.luks.devices.luksroot = {
   name = "root";
   device = "/dev/disk/by-uuid/(encrypted partition UUID, not volume)";  # sda2
   preLVM = true;
   allowDiscards = true;
   };

4. nixos-install

Expected: Install to proceed as normal

Actual: Error appears partway through install when it reaches luksroot.nix

What if you try changing name = "root"; to name = "luksroot";, or devices.luksroot to devices.root?

[eyJhb]

@ergose is this still a issue?

"luksroot" worked for me!

Given that I followed https://gist.github.com/martijnvermaat/76f2e24d0239470dd71050358b4d5134 to the letter and would have expected the name to be "root" (created with lvcreate -l '100%FREE' -n root vg), maybe the issue is still relevant?

Anyway, you helped @cole-h, thanks!
