ZFS with history

I stumbled upon a blog today and it highlighted that the ZFS file system contains the history of all commands executed with respect to the ZFS pool.

Below is the output of the zpool history for my previous blog

# zpool history zpool
History for 'zpool':

2007-03-27.17:51:24 zpool scrub zpool
2007-03-27.17:53:23 zpool replace zpool /zdisk/z18 /zdisk/z18new
2007-03-28.11:31:24 zpool scrub zpool

IMO, it is a very nice feature 'cos it captures the life cycle of the ZFS pool (almost). It would be even better if this information is written to the OS so that it can really cover the whole life cycle, including the 'zpool destroy'.
