Good find.  I honestly thought this worked as expected versus as
written.  In fact, I *thought* secondary, tertiary, etc. kernels were
installed as /boot/kernel.KERN2, /boot/kernel.KERN3 (using the example
above).

Although, I may be misremembering, and 'kernel.KERN2.txz' may be created
instead, although not installed/extracted.  Though, we are going back at
least seven years, and I do not even remember what I had eaten for
dinner last night, so there's that...
