I don't think I saw this.. Though my kernel refused to probe my
swap partition so I had to dkctl add it in a boot script in order
for it to be recognized.. Not sure why since 'gpt show' did show
it. However, 'gpt show' did indicate that it was the same index as
the GPT secondary partition table (both were at indx '4') so when I 
saw that, it triggered my first tear-down/restart...

I didn't start with a fresh-out-of-the-box install though. I always shrunk
the OSX partition with diskutil first.
