| |
Instead of forcing the user to manually load the module do it automatically.
For example this avoids the following error when using nbd-client:
$ nbd-client localhost 10809 /dev/nbd0 ... Error: Couldn't resolve the nbd netlink family, make sure the nbd module is loaded and your nbd driver supports the netlink interface.
