+The installer creates a ZFS pool `rpool`. When selecting ZFS, no swap space is

+a swap zvol after installation, though the latter can lead to problems
+(see <<zfs_swap,ZFS swap notes>>).

+Defines the `ashift` value for the created pool. The `ashift` needs

+
+`checksum`::

+Defines which checksumming algorithm should be used for `rpool`.

+`copies`::
+
+Defines the `copies` parameter for `rpool`. Check the `zfs(8)` manpage for the
+semantics, and why this does not replace redundancy on disk-level.
+
+`hdsize`::
+
+Defines the total HD size to be used. This way you can save free
+space on the HD(s) for further partitioning (e.g. for creating a swap-partition).
+`hdsize` is only honored for bootable disks, i.e., only the first disk or
+mirror for RAID0, RAID1 or RAID10, and all disks in RAID-Z[123].
