[Nix-dev] [haskell-ng] nix-shell mass rebuild

Tue Mar 31 18:42:58 CEST 2015

Hello,

I'm using only nix pkg manager on ubuntu 14.04. Last execution of nix-shell
was couple of weeks ago.

After channel update (nix-channel --update) on today, I only updated 'nix'
pkg manager manually because nix tried to update cabal2nix 2.x -> 1.7.x .

Then tried nix-shell on my project directory and got so many drv rebuild.

$ nix-shell shell.nix --dry-run
these derivations will be built:

               license = stdenv.lib.licenses.unfree;
             }) {};
in
  pkg.env

I have extra-binary-caches for haskell-ng in /etc/nix/nix.conf

$ cat /etc/nix/nix.conf
extra-binary-caches = http://hydra.nixos.org http://hydra.cryp.to
$

Should I rebuild all as nix-shell says? Why updates are not in
binary-caches?

Thanks.
