netfs init script on RHEL 5 and 6 always mounts netdev devices after NFS devices

Issue

• When the system reboots, the NFS devices are mounted before the _netdev devices and a umount/remount of the NFS devices is required to ensure the desired mount sequence.

  Example /etc/fstab entries:

/dev/vg1/vol /mnt ext3 _netdev 1 2
nfs-server:/nfsexport /mnt/nfsmount nfs defaults 0 0

• If there is an interdependency between mount points, e.g. mounting an NFS device in a sub directory of a _netdev device's filesystem hierarchy, this results in the undesirable situation where the NFS device is mounted before the _netdev device.
