fstab mount wait for network

Adding _netdev to the mount options in /etc/fstab might be sufficient.

Mount units referring to local and network file systems are distinguished by their file system type specification. In some cases this is not sufficient (for example network block device based mounts, such as iSCSI), in which case _netdev may be added to the mount option string of the unit, which forces systemd to consider the mount unit a network mount.

Additionally systemd supports explicit order dependencies between mount entries and other units: Adding x-systemd.after=network-online.target to the mount options might work if _netdev is not enough.

See the systemd mount unit documentation for more details.

Add _netdev to the /etc/fstab entries in question. From the manpages for `mount(8)':

_netdev The filesystem resides on a device that requires network access (used to prevent the system from attempting to mount these filesystems until the network has been enabled on the system).
