That is a simple answer... ;-) But don't you think that two commands with different results on the output (df), zfs list and zpool list with four different outputs if the pool is using mirror redundancy or raidz is a problem? The fact the zpool list shows the right value of available space using mirror, and not using raidz (on raidz configuration the parity is accounted, and using mirror don't). I think this is an issue that just refering a user to the faq does not help.
