From f1eb192e264a10ccbc5b303f72347a9c846965af Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Tue, 1 May 2018 10:44:09 +0200 Subject: [PATCH] download/git: add warning not to use our git cache We really want the user not to use our git cache manually, or their changes (committed or not) may eventually get lost. So, add a warning file, not unlike the one we put in the target/ directory, to warn the user not to use the git tree. Ideally, we would have carried this file in support/misc/, but the git backend does not have access to it: the working directory is somewhere unknown, and TOPDIR is not exported in the environment. So, we have to carry it in-line in the backend instead. Signed-off-by: "Yann E.
