From d824cbba02a4061400a0e382f9bd241fbbff34f0 Mon Sep 17 00:00:00 2001 From: Thomas Rast Date: Sat, 27 Jun 2009 17:58:46 +0200 Subject: Convert existing die(..., strerror(errno)) to die_errno() Change calls to die(..., strerror(errno)) to use the new die_errno(). In the process, also make slight style adjustments: at least state _something_ about the function that failed (instead of just printing the pathname), and put paths in single quotes.
