Added automatic driver loading (#469)
Browse files Browse the repository at this point in the history
* Added automatic driver loading
When the config file sets enable_autoload_drivers=1, the installer will
enable driver loading on hotplug events using mdev.conf, and it will try
to load drivers for already connected devices.

* * Fixed modprobe for module aliases that contain whitespace

* * Removed enable_autoload_drivers option, enabling it by default
  • Loading branch information
