Isn't the above moot if you have a no usb devices and static dev:
1) changing owner/group/permissions are persistent, i.e. set it once
and be done with it
2) isn't that mostly useful for if you have lots of disks, say more than 5.
If you just have one or two, you don't need that.
Also that could be generated by a script which you run manually when
needed.
3) can't you do ifrename from rc.local
So unless you change things you don't need udev.
Unfortunately, many things have grown to dependent of udev which
technically isn't.
