Yes, you really want to reboot to single-user mode to installworld, even though the installworld works fine in multi-user mode. The problems is that you are installing a new userland while running the old kernel. The next time you re-boot it is possible that the kernel won't work. You can boot with kernel.old, but that leaves you with a partly functioning system since the kernel and userland are not only out of sync, but in the "wrong" way, and it's virtually impossible to "uninstallworld". You usually have to re-install! That all said, many people do the entire installation without a reboot and do it remotely with no console access. (I've done it and probably will again.) It USUALLY works, but when it fails, you are in VERY deep weeds! R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
