[OpenIndiana-discuss] ZFS; what the manuals don't say ...

[Gregory S. Youngblood]

Probably should use find -type f to limit to files and also cp -a to maintain permissions and ownership. Not sure if the will maintain ACLs.

For the truly paranoid, dont delete the original file so early, rename it, move the temp file back as the original filename, then compare md5 or sha checksums to make sure they are the same, only deleting the original file if the two sums match.
