OK, here's a question that I've been thinking about, and this brings
it to mind:

Have any of the changes in the last six months to a year required new
boot blocks?

I'm still running 1.28 boot blocks with a 1.2.1 kernel.  In addition
to this change, I remember someone committing something not too long

So, will I still be able to boot a totally current kernel with old
