[Nix-dev] nixops: argument list too long

[Eike]

nixops --version says "1.3.1". I'm running NixOS 16.09pre85931.125ffff
(unstable channel) and installed nixops using `nix-env -i nixops'. I
noticed that when I remove all system packages from configuration.nix,
it doesn't error anymore. So I guess it's because the closure is too
large? This would be too bad for me, because I hoped to manage some
(physical) desktop machines with nixops that have many system packages.

Here is the output of nixops info -d lenni. For me it doesn't provide
any hints regarding this problem:

    Network name: lenni
    Network UUID: 745c1905-5050-11e6-b200-90e6baf47cb4
    Network description: Lenni
    Nix expressions: /home/eike/workspace/projects/confnix/systems/lenni/deploy.nix
    
    +-------+---------------+------+---------------------------------------------------+------------+

    +-------+---------------+------+---------------------------------------------------+------------+
    | lenni | Up / Outdated | none | nixops-745c1905-5050-11e6-b200-90e6baf47cb4-lenni |            |

Thanks a lot and kind regards
