[Nix-dev] Why does my system rebuild rustc and cargo?

[James Cook]

I have no idea what is happening. But here are some questions that come to mind:

* Is the path always exactly the same
(/nix/store/iybrbljd5nzk4n4zmfgvibrhh2zjvp04-rustc-1.4.0.drv) or does
it change?

* If the answer is "always the same", then does the derivation
successfully get built? What I mean is, when you a message like
"building path(s) ‘/nix/store/XXX", then after that's done, does
/nix/store/XXX exist? (Note: this is not the same as the
/nix/store/iybrbljd5nzk4n4zmfgvibrhh2zjvp04-rustc-1.4.0.drv path! Look
for a different path when you see the "building path(s)" message.)
