commit f9aed0009df71f4c77d1cf6dcf5da0ceb14bc45f
Author: Andreas Beckmann <anbe at debian.org>
Date:   Wed Jun 17 12:21:15 2015 +0200

    p: ensure /etc/mtab exists in the chroot
    
    mount in sid no longer creates a missing /etc/mtab -> ../proc/mounts symlink
    but commands like df rely on /etc/mtab
