Just to provide contrast, NFS has a config file which can provide
certain defaults for mounted filesystems. However it doesn't require a
udev event to achieve this.
Instead, it provides "/sbin/mount.nfs" which imposes the defaults at
mount time, rather than just after mount time.
There could, conceivably, be an "/sbin/mount.xfs" which read the config
file and set all the defaults concurrently with the mount operation.
I'm not necessarily saying this is a better way to go, but I agree with
the need to be sure, and this provides evidence that other approaches
are possible and worth considering.
