Hotplug lets you plug in new devices and use them immediately. That means that users won't need to learn so much system administration, since the Linux system will at least partially autoconfigure itself. Initially, hotplug included support for USB and PCI (Cardbus) devices, and could automatically configure some common network interfaces. Updated versions include IEEE 1394 (Firewire/i.Link) support and can download firmware to USB devices that need it.
Multicast BOOTP Java server and C/Linux client's goal is to implement the BOOTP/DHCP protocol through multicast rather than broadcast. Sun's Java networking API offers multicast socket communication objects, allowing you to create a platform independent IP interface configuration utility. Eventually, such utilities may become a fully featured multicast DHCP server. Any ideas on how to support existing BOOTP broadcast client requests are welcome. See the Multicast HOWTO at http://www.linuxdoc.org/HOWTO/Multicast- HOWTO.html.
SoL (Server optimized Linux) is a Linux distribution completely independent from other Linux distributions. It was built from the original source packages and is optimized for heavy-duty server work. It contains all common server applications, and features XML boot and script technology that makes it easy to configure and make the server work.
