Owner

The bug in the following code snippet was fixed by cl/2794, but this genre of problem persists, and we need the case hack to be store local in the future.

lix/lix4 » nix build --impure --expr 'with import <nixpkgs> {}; runCommand "lol" {} "mkdir $out; > $out/foo; > $out/fOO"'
lix/lix4 »·nix store ls --use-case-hack --store ssh-ng://jade@localhost $(readlink ./result)
./fOO
./foo~nix~case~hack~1

This is caused by use-case-hack being a global setting and not respecting whether the current output target actually should be case hacked in the first place. Fixing this to be a setting on the store in question and no longer reading that setting directly in the NAR serializers/deserializers would be a valuable refactor in order to implement #628.

Figure out what circumstances lead to nix~case~hack~1 getting into a NAR #726
