Part of the archiving process is to generate checksums (I happen to use
MD5), and store them with other metadata about the digital object in

digital object over time.
Wouldn't it be helpful if there was a utility to access/read the
checksum data created by ZFS, and use it for those same purposes.
Doesn't ZFS use block-level checksums?
Hoping to see something like that in a future release, or a command line
utility that could do the same.
It might be possible to add a user set property to a file with the md5sum and
a timestamp when it was computed.
But what would this protect against? If you need to avoid tampering, you
need the checksums offline anyway - cf. tripwire.
