SMPng is a *major* change, with lots of things associated with it. For instance, /dev/random uses kernel threads (which need SMPng) to collect entropy from various device drivers, so hopefully we get cryptographically secure random numbers for cheap. The functionality of md, mfs and vn have been merged, and improved. devfs not only works, but is the default. This means that MAKEDEV is no longer needed for the standard install. http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
