I suspect you omit certain details, such as running grub-mkconfig or otherwise updating your grub (or other bootloader) configuration prior to the first reboot. then i periodically update the system by: sudo emerge -avDuNt --quiet-build=y --keep-going=y @world problem is: when the gentoo-source kernel gets updated by emerge, it does not use my genkernel's new configs. questions: 1. What's going on? 2. How to fix it? Unless I'm missing something about what you are doing, simply emerging a new gentoo-kernel version does nothing except install the sources, it doesn't build the new kernel. You would still need to run genkernel again for that new version.
