/usr/src/sys/conf/Makefile.kern.inc has a common way (I show below).

From Makefile.kern.inc, I adjusted to use KERNOBJDIR and kconf since
BUILDING uses that:
rm -f /onetbsd
ln /netbsd /onetbsd
cp KERNOBJDIR/kconf/netbsd /nnetbsd
mv /nnetbsd /netbsd
From NetBSD Guide: "At the end of its job, build.sh will print out the
location where the new compiled kernel can be found."
mv /netbsd /netbsd.old
mv netbsd /
Or maybe it should be in the EXAMPLES section at end instead.
