_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). 

remount 
Attempt to remount an already-mounted file system. This is commonly used
to change the mount flags for a file system, especially to make a readonly
file system writeable. It does not change device or mount point.
