-config HOTPLUG
- bool "Support for hot-pluggable devices"
- help
- Say Y here if you want to plug devices into your computer while
- the system is running, and be able to use them quickly. In many
- cases, the devices can likewise be unplugged at any time too.
-
- One well known example of this is PCMCIA- or PC-cards, credit-card
- size devices such as network cards, modems or hard drives which are
- plugged into slots found on all modern laptop computers. Another
- example, used on modern desktops as well as laptops, is USB.
-
- Enable HOTPLUG and build a modular kernel. Get agent software
- (from <http://linux-hotplug.sourceforge.net/>) and install it.
- Then your kernel will automatically call out to a user mode "policy
- agent" (/sbin/hotplug) to load modules and set up software needed
- to use devices as you hotplug them.
