It's NOT just a convenience!
Another explanation of this appears to be in order:
"make buildkernel" makes use of the special knowledge make has of the
new, uninstalled system to build the kernel using the updated
tools. This assures that the kernel and user files are synchronized.
ALWAYS use buildkernel/installkernel when you have updated sources and
done a fresh buildworld. NEVER use buildkernel/installkernel if you
have not previously done a buildworld. If /usr/obj is not populated,
buildkernel will fail.
If you are simply modifying the kernel configuration and rebuilding,
the best way is to:
cd /sys/i386/conf
config YOURKERNELNAME
and follow the instructions provided. This does not require that the
/usr/src or /usr/obj trees be populated.
If you have previously done a buildworld and installworld and have not
updated your sources, the kernel may be built either way with
identical results, but buildkernel/installkernel takes a bit longer.
I hope that's clear. If you are confused, get back to me and I'll try
to clarify.
