It's mostly in user-space, lighter-weight, and more configurable. It relies on a clever use of other existing kernel features (ramfs, hotplug callouts, sysfs) rather than being a big chunk of special purpose code wired into kernel space. Also, the naming policy is entirely in user-space, there are no wacky device naming conventions in the kernel where they can cause big flamewars. -Miles -- `Suppose Korea goes to the World Cup final against Japan and wins,' Moon said. `All the past could be forgiven.'
