[Nix-dev] inconsistent kernel versions

[Lluís Batlle]

"nix-build -A system mynixostree" fails to me this way:
inconsistent kernel versions: 2.6.28.10-default
2.6.28.9-default

It's not the same nixos tree as in this computer... I'm trying to
build the nix store paths for the nixos of another computer (I set the
environment for nix-build to take the proper configuration.nix,
config.nix and nixpkgs), and it worked for me until this.

Any help?

Lluís.
