Hotplug
Contents
The hotplug and device handling subsystem has undergone significant changes in Redhat Enterprise Linux 5. The udev method now handles all module loading, both on system boot and for hotplugged devices. The hotplug package has been removed, as it is no longer needed.
Hotplug helpers via the /etc/hotplug, /etc/hotplug.d, and /etc/dev.d directories have been removed and converted to udev rules.
