All my systems run custom-configured kernels built from on stable gentoo-sources. All I've ever done for a kernel upgrades is to go into the new kernel source dir and do the following: # zcat /proc/zconfig >.config # make oldconfig # make # make install For the past 20+ years, that has always worked fine for minor version changes (e.g. 5.15.x ⇒ 5.15.y) There have been a few major upgrades in the past 20 years when a large kernel subsystem change required some sort of manual intervention with a "make menuconfig". But, I can't actually remember the last time it happened (it's been years). -- Grant
