If you do not use ZFS, you can skip this message.

This case changes the zfs list command to omit snapshots by default.
Instead, the zfs list command will display only filesystems and volumes.

On systems with large number of snapshots, the snapshot info can flood
the output, making the default zfs list command less useful in the
case where the user is not interested in information about snapshots.

A new pool level property called "listsnaps" permits control of the
zfs list output for that pool.  The value for the new property can be
set at pool creation time and import time, and can be changed later
with the "zpool set" command.

The -t option to the zfs list command takes precedence over the value
of the "listsnaps" property so "zfs list -t snapshot" or "zfs list -t all"
will display all snapshots including those associated with pools where
the "listsnaps" property is off.
