Rebuilding world doesn't rebuild the kernel by itself - it only installs the sources and (if you have the symlink USE flag set) resets the /usr/src/linux link to point to the new source tree. So no, you don't have to reboot after rebuilding world. I would, myself, but then mine are home machines, not production servers. On the other hand, you may run into problems if you do much emerging with usr/src/linux pointing to a kernel version other than the one that's running. It depends on whether you have packages that include their own kernel modules, like nvidia-drivers or virtualbox. -- Rgds Peter.
