Bug#737759: hurd: Add init.d script to create /var/run/mtab

[Petter Reinholdtsen <pere@hungry.com>]

Package: hurd
Version: 1:0.5.git20140203-1
Severity: important
Tags: patch

At the moment in unstable when booting Hurd using sysvinit, df and
friends do not work because /var/run/mtab do not exist.  It should point
to /proc/mounts, and this is done in /etc/hurd/rc when not booting using
sysvinit.

Instead of creating the symlink in /etc/hurd/rc, I suggest to create a
new init.d script to create this symlink, and drop the code from
/etc/hurd/rc.  The following script is tested and found to be working
well.  It creates /run/mtab because /var/run is a symlink to /run.

#! /bin/sh
