True but there are some bad assumptions that people can be led to
believe. One of them is that ZFS is somehow "more robust" in a
non-power-protected single-provider NAND-flash based storage system.
Uh uh. Yes, a scrub (or just checksum check on the read) will catch the
"aw crap!" situation where write amplification and read/rewrite hoses
you during a power failure but there's nothing zfs can do to fix it
since there's no second copy available. If the file that gets hit by
that read/rewrite hosing is /boot/kernel/kernel (or a required .ko, say,
zfs.ko?) then the system still doesn't boot at all.
