OK, I understand.  I think I will go ahead and change tail to tail -n
50.  That should provide plenty of feedback, eh?

I thought it would be a good idea to install both GENERIC and CUSTOM
kernels, so that I could boot to GENERIC if necessary.

So, if I add KERNCONF=GENERIC CUSTOM to make.conf, then the generic
kernel is installed as /boot/kernel, and I can cp /boot/kernel
/boot/kernel.GENERIC.

Then I can do installkernel KERNCONF=CUSTOM, and that will install the
custom kernel as /boot/kernel, and that will be the default to boot...?
