It's confusing because I wrote the mini root to the B partition and
booted the kernel from the B partition but that kernel mounted the A
parition as it's root...

(I was assuming, incorrectly, that the boot program would communicate the
boot parition to the kernel)

Well, it requires one to use the "-a" argument if you boot from something
other than the A parition.  I guess I liked the old way of passing the
info along to the kernel, just for safety's sake...

-a works.  it asks you for the root.
