From cc84d63a42e31c2afa884fc78610a65ab8ecc06a Mon Sep 17 00:00:00 2001 From: "Daniel P. Berrange" Date: Fri, 20 Oct 2017 15:02:43 +0100 Subject: [PATCH] build: allow setting a custom GIT binary for transparent proxying MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Some users can't run a bare 'git' command, due to need for a transparent proxying solution such as 'tsocks'. This adds an argument to configure to let users specify such a thing: ./configure --with-git="tsocks git" The submodule script is also updated to give the user a hint about using this flag, if we fail to checkout modules.
