Cannot build cachix

[nomeata]

In cachix/cachix#184 (comment) it was suggested that

NIX_PATH=nixpkgs=https://github.com/NixOS/nixpkgs/archive/88ae8f7d.tar.gz nix-build --no-link survey/default.nix -A haskellPackages.cachix

would build a static version of cachix. Unfortunately, it fails here:

~/build/haskell/static-haskell-nix $ NIX_PATH=nixpkgs=https://github.com/NixOS/nixpkgs/archive/88ae8f7d.tar.gz nix-build --no-link survey/default.nix -A haskellPackages.cachix -j8 --builders ''

Hmm, the number of test failures of servant-auth-server vary from run to run. Probably a problem with upstream's test suite being not very robust. Likely haskell-servant/servant-auth#115.

[nomeata]

Indeed, this is just haskell-servant/servant-auth#115 and just retrying the build in a loop eventually made it build cachix!
