# Description:       Now that TCP/IP is configured, mount the NFS file
#                    systems in /etc/fstab if needed. If possible,
#                    start the portmapper before mounting (this is needed for
#                    Linux 2.1.x and up).
#
#                    Also mounts SMB filesystems now, so the name of
#                    this script is getting increasingly inaccurate.
