[Nix-dev] Hydra nixpkgs-unstable channel lagging behind?

[Peter Simons]

Hi,

nixos-rebuild wants to compile lots of packages that I would expect to
get from hydra in binary form (such as Ghostscript), but apparently
Hydra doesn't have them? My manifest seems to be up-to-date, though:

  # nixos-rebuild pull
  fetching list of Nix archives at `http://nixos.org/releases/nixpkgs/channels/nixpkgs-unstable/MANIFEST.bz2'...
    % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                   Dload  Upload   Total   Spent    Left  Speed
  100   411  100   411    0     0   4448      0 --:--:-- --:--:-- --:--:--  8744
    0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0

Am I doing something wrong? Or is Hydra simply lagging behind for some
reason?

Take care,
Peter
