The existing comment is incomplete and should be updated to mention the other effects. The option pre-dates udev and so the "newer" interlocking there ought to be mentioned. The description of 'advanced' could also be updated to explain that that means you should not change it unless you know exactly what you are doing! The option exists to simplify some development, test and support scenarios where you want to have two or more distinct userspace LVM instances running on a single machine. For example, to try to reproduce a certain type of user-reported bug you might set up a temporary /dev in a non-default location with contents that match that user's system and point the tools at that using this option.
