- Mount ZFS snapshots with MNT_IGNORE flag, so they are not visible in regular

  df(1) and mount(8) output. This is a bit smilar to OpenSolaris and follows
  ZFS route of not listing snapshots by default with 'zfs list' command.
- Add UPDATING entry to note that ZFS snapshots are no longer visible in
  mount(8) and df(1) output by default.
