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).
