Running nixos-install from SOQuartz SD image gives ` 'flakes' is disabled` error

[msgilligan]

When I try to use the SoQuartz SD Image to install NixOS to NVMe, I get the following error:

error: experimental Nix feature 'flakes' is disabled; use '--extra-experimental-features flakes' to override

Using sudo NIX_CONFIG="experimental-features = nix-command flakes" nixos-install seems to work-around the problem, but when installing to NVMe from other NixOS installer images this isn't required. It seems like installers created with this image require flakes without flakes being enabled.

Normally, to enable flakes I would edit /etc/nixos/configuration.nix (NixOS) or /etc/nix/nix.conf (Nix package manager only), but the first one didn't exist and the second strongly discouraged modification.

I don't think this is specific to the Quartz image, rather to sdcard images with flake configs. Having the same issue on rock pi 4c

@msgilligan do you know an elegant solution to this problem? If not I can just add instructions to the readme.

Not off the top of my head. I would say just add the instructions for now.
