    Work around an apparent 'schroot' anomaly
    
    If the values of both 'users' and 'groups' are double-quoted in
      /etc/schroot/chroot.d/*.conf
    e.g.
      users="greg"
      groups="greg"
    then the specified normal user cannot enter the chroot:
    
    $schroot --chroot=centos7lmi --user=greg
    E: Access not authorised
    I: You do not have permission to access the schroot service.
    I: This failure will be reported.
    
    Prefixing that failing command with 'sudo' makes it work as expected.
    
    This might look like a problem with
     (1) the setuid bit on /usr/bin/schroot, or
     (2) permissions on the chroot's root directory (0700, e.g.),
    but the same user can enter other chroots, which rules out (1), and
    (2) is ruled out by inspection:
      $ls -ld /srv/chroot/centos7lmi
      drwxr-xr-x 17 root root 12288 Oct  9 15:56 /srv/chroot/centos7lmi
