Title:
  auto.net does not handle mutliple mount points from a remote

Status in “autofs” package in Ubuntu:
  New

Bug description:
  When using auto.net and mounting multiple remote exports, only one mount works and autofs steps onto the other mounts.
  The problem appears in /proc/mounts (see details in walk-thru below)
