I've discovered another issue with both the current code and the previous
versions of the patch. So another version is at the same URL:

The problem was with gang blocks on a raidz vdev. zio_read_gang would pass a
NULL bp to vdev_raidz_read, but

And I am actually wondering about -fno-unit-at-a-time option.
In my opinion this is an anti-optimization option and it can actually increase
a size of a final binary. In fact, it looks like the option was introduced to
boot2 in r132870 in

In any case, size isn't an issue for any of gptboot, gptzfsboot or

gptboot and gptzfsboot? It would be more convenient to have a
single GPT bootstrap that
