From 3719b2fe554adc2f7a34a16b90f6894f299aab3c Mon Sep 17 00:00:00 2001 From: =?utf8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Sun, 14 Feb 2010 22:44:45 +0700 Subject: [PATCH] Add test for using Git at root of file system MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This kind of test requires a throw-away root filesystem so that it can play on. If you have such a system, go ahead, "chmod 777 /" and run this test manually. Because this is a dangerous test, you are required to set an env variable, and not to use root to run it. Script prepare-root.sh may help you set up a chroot environment with Git test suite inside. You will need Linux, static linked busybox, rsync and root permission to use it.
