Once you've downloaded all the sources, if you ever need to rebuild on a
different machine, you can reference these already downloaded sources,
amiright? In effect, you've created own local mirror.

Would you rather freeze the dependencies as part of whatever
you're building, or have a persistent mirror (IPFS) of all
packages that Nix ever makes available?

How would you go about (pre)fetching every source in the nixpkgs

In the last couple days:
* GNU bash silently updated patch 42
(https://github.com/NixOS/nixpkgs/issues/11475)
* OpenSSL moved the 1.0.2d release to the "old" directory
(breaking the URL)
(https://github.com/NixOS/nixpkgs/commit/51a5f49d700890a93c36dd50e5eca4bf6ee6966b)
These kind of breakages introduced by the external world erode
the promise of Nix that attracted me as a developer: reproducible
builds into the future. In this respect alone, Nix + a fixed
nixpkgs checkout provides little/no advantage over building in a
VM: both work indefinitely as long as you don't introduce new
dependencies.
I intend to build/test a sort of hermetically sealed Nix where
all dependencies are frozen in time (saved somewhere). I suspect
I'm not alone in wanting this
(http://permalink.gmane.org/gmane.linux.distributions.nixos/18611).
I'd appreciate any tips/guidance/references to related work
before I begin.
