disko-install: Use nix store of the new NixOS installation #1209
Description
When installing NixOS via disko-install on a USB live image, if the NixOS configuration (in this case a nixosConfiguration in a flake) that is larger than the TmpFS nix-store, installation fails.
Would it be possible to use the nix store of the created root in /mnt instead of the one in the live image?
