Thank you for the feedback Michael.
"zcat" was my acronym for a special ZFS aware version of "cat" and I did
not know that it was an existing command. Simply forgot to check. Should
rename if to "zfscat" or something similar.

The trick should be that the zcat userland app already knows that it
will generate duplicate files so data read and writes could be avoided
all together.
you'd probably be better off avoiding "zcat" - it's been in use since
almost forever, from the man-page:
zcat
The zcat utility writes to standard output the uncompressed
form of files that have been compressed using compress. It
is the equivalent of uncompress-c. Input files are not
affected.

cheers
