​I notice that nix-env in current-system/sw directory is still nix-1.8. I
am not sure why it is not updating even though in my root environment, I
have nix-1.11.6. Any clue, how to fix this?

[root at localhost:/var/run/current-system/sw/bin]#  nix-store -q --references
/var/run/current-system/sw | cut -d'-' -f2- | grep nix
nix-1.8
nixos-install
nixos-version
nixos-build-vms
nixos-checkout
nixos-option
nixos-rebuild
nixos-manpages
nixos-help
nixos-generate-config
nixos-container
