No, you aren't. If you don't create a partition table in the first
place, there's no possibility for partition boundaries to be mis-aligned
in regard to the physical sector or erase block size of the underlying
blockdevice. You could probably still get it wrong if you chose (if
that's even possible, I don't know for sure off-hand) a very weird
non-power-of-two chunk size that happens to interfere with the sector
size of your disks in a bad way, but since md's default chunk sizes are
rather large powers of two, you'd have to put some effort into screwing
up (if that is at all possible, as I mentioned before) ;)
