.. and remember that Augeas solves the problem of having traditional
config files that can be edited in a structured way, including
preserving all the comments and whitespace and everything else.

  # augtool match '//files/etc/ntp.conf/server[*]'
  /files/etc/ntp.conf/server[1] = 0.fedora.pool.ntp.org
  /files/etc/ntp.conf/server[2] = 1.fedora.pool.ntp.org
  /files/etc/ntp.conf/server[3] = 2.fedora.pool.ntp.org
  /files/etc/ntp.conf/server[4] = 3.fedora.pool.ntp.org
  # augtool <<EOF

  Saved 1 file(s)
  # augtool match '//files/etc/ntp.conf/server[*]'
  /files/etc/ntp.conf/server[1] = ntp.annexia.org
  /files/etc/ntp.conf/server[2] = 1.fedora.pool.ntp.org
  /files/etc/ntp.conf/server[3] = 2.fedora.pool.ntp.org
  /files/etc/ntp.conf/server[4] = 3.fedora.pool.ntp.org

[ then look at /etc/ntp.conf to verify that all comments and
formatting are preserved ]
