Add test for using Git at root of file system
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. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

|

|

This test requires write access in root. Do not bother if you do not

have a throwaway chroot or VM.
|

|

Script t1509/prepare-chroot.sh may help you setup chroot, then you
|

can chroot in and execute this test from there.
