[Nix-dev] upgrading packer

[Samuel]

Hi,

I took a brief look into upgrading packer in nixpkgs, but it seems
that it has a long list of hardcoded dependencies
(https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/tools/packer/deps.nix).
Is there any automation to bump those or is it a manual process?

In the meanwhile I've written an expression that downloads the
official binaries:

https://github.com/samuelrivas/monorepo/blob/packer/nix/pkgs/development/tools/packer/default.nix

But I assume that's not a change that I should pull request. Just let
me know otherwise.

Best
