From f656cafd4c290db7abb1ac1d357696ffdc1793b7 Mon Sep 17 00:00:00 2001
From: Jim Meyering <meyering@redhat.com>

Subject: Avoid test failures when root (/) is not readable.

* tests/test-lib.sh (require_readable_root_): New function.
* tests/misc/pwd-long: Skip this test when / is unreadable.
* tests/du/slash: Likewise.
This is required at least for Mandrake/Mandriva in "secure" mode.
