OpenZFS 8906 - uts: illumos rootfs should support salted cksum
Porting notes:
* As of grub-2.02 these checksums are not supported. However, as
pointed out in #6501 there are alternatives such as EFISTUB which
work and have no such restriction. A warning was added to the
checksum property section of the zfs.8 man page.
