You can construct one with eg, `(MountOpts ["defaults"])`. But, since `MountOpts` is a `Monoid`, and "defaults" is the default of an empty `MountOpts`, you can more simply use `mempty` to get the default one: Mount.mounted "nfs" "192.168.1.100:/mnt/usb1" "/mnt/nfs" mempty Propellor.Property.Mount was mostly written for use by some other properties, and so doesn't really target the end user as much. And, I notice, its `mounted` property doesn't check if the device is already mounted and so will try to re-mount unnecessarily. I'm not sure if manually driving the mount command makes the most sense; wouldn't it be better to have a property that updates /etc/fstab? """]]
