​Correct.  At least, that's the way it's worked in the past, and something
I've used quite a bit on FreeBSD 7-9.  I always have GENERIC and a custom
kernel listed in KERNCONF, with my custom kernel listed first.
KERNCONF="FIREWALL GENERIC" for exmaple.  That way, my custom kernel is
installed as /boot/kernel, and GENERIC is installed as
/boot/kernel.GENERIC, which provides me with a fall-back in case I screw
something up with my custom kernel (happens frequently).  :)

I used to do it manually using two separate installkernel steps using an
env var to specify the installation directory (/boot/GENERIC) (forget the
name of that var right now), but switched to using the automatic
installation behaviour when it became available.  Simplified things a bit.

I haven't compiled a kernel on 10+ yet; hopefully the behaviour hasn't
changed.  ;)
