By compiling 15-STABLE from latest available 14.3 getting sources via

git clone https://git.freebsd.org/src.git /usr/src
cd /usr/src
git checkout stable/15
etcupdate extract -> gives error
etcupdate diff -> gives error
cp  /usr/src/sys/amd64/conf/GENERIC ~/FBSD15
vi ~/FBSD15
ln -s ~/FBSD15  /usr/src/sys/amd64/conf/FBSD15
make buildworld KERNCONF=FBSD15
make kernel KERNCONF=FBSD15
make installkernel KERNCONF=FBSD15
reboot
etcupdate -p -> fails
make installworld KERNCONF=FBSD15
etcupdate -B -> fails
reboot

Realy standard, except the edited kernel configuration, to match some
drivers nowmaly not build, or build with different options, just to make
some exotic hardware run,
