| |
| 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 KMOD, and build a modular kernel. Get agent |
| software (at <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. |
