Upstream patch for df(1) on top of v8.23, to be removed with v8.24. http://git.sv.gnu.org/cgit/coreutils.git/commit/?id=3ab3c7bb24b8 From 3ab3c7bb24b86ef2d2fede9fe26e3ee585db5411 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?P=C3=A1draig=20Brady?=
Date: Mon, 27 Oct 2014 23:37:08 +0000 Subject: [PATCH] df: ensure -a shows all remote file system entries commit v8.22-125-g9d736f8 printed placeholder "-" values for device names that didn't match the preferred device name for a particular mount point. However that was seen to erroneously suppress values for aliased host names or exports, common with remote file systems. * src/df.c (me_for_dev): Rename from devname_for_dev() so that we can determine the remoteness as well as the name for the preferred mount entry. (get_dev): Don't output place holder values when both current and preferred mount entries are remote.
