From 3a38d0f3565a02c034c29b264aceb0eb78dac005 Mon Sep 17 00:00:00 2001 From: Shea Levy Date: Thu, 6 Feb 2014 11:52:03 -0500 Subject: Add the nix-store --serve command This is essentially the substituter API operating on the local store, which will be used by the ssh substituter. It runs in a loop rather than just taking one command so that in the future nix will be able to keep one connection open for multiple instances of the substituter.
