From fcc4134a7b76d82d39dea635c41ec593a41d6d19 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sun, 22 Feb 2009 19:29:48 +0800 Subject: [JOBS] Do not close stderr when /dev/tty fails to open As it stands if we fail to open /dev/tty we end up closing stderr after saving it at a higher fd. Thanks to David van Gorkom for reporting this.
