Pushing changes to udev driver repos


My understanding of udev is that its a way to dynamically manage all connected/disconnected device drivers on a Linux system, and that libudev is the actual Linux library that implements the udev API/designs. If that's correct, then I have to imagine that udev allows you to configure a "repo" where device drivers can get installed, so that as soon as a hotpluggable device is connected to it, udev finds that device's driver (in this repo) and loads it.


If that's correct, then where is this repo and is that location configurable? Can it be configured to look for drivers in a remote location (using HTTP, TCP, etc.)?


Also, does udev/libudev, offer a way to dynamically update/upgrade device drivers at runtime? It would be nice to push device driver updates to this repo and then have udev automatically release/unload the driver, overwrite the old driver with the new/updated one, and then reload that new driver.
