Um. Because no good reason? This is both fast and produces the smallest
size.
There was some problem with it months ago, and I had discarded it as an
option. But clearly that was wrong!
I remembered / re-discovered the reason: it fails in virt-install with
"fstrim: /: FITRIM ioctl failed: Operation not supported".
I should probably figure out *why* rather than just avoiding it, though. :)
