Log:
MFC zfs manpage update
(r227646, r227648, r227649, r227752, r228019, r228045, r228054, r228055)
MFC r227646 (partial):
Update and desolarization of zfs(8) and zpool(8) manual pages:
- synchronized to match new vendor code (Illumos rev. 13513) [1]
- removed references to sun commands (replaced with FreeBSD commands)
- removed ATTRIBUTES sections
- updated SEE ALSO sections
- properly updated copyright information (required by CDDL)
zfs(8) only:
- replaced "Zones" section with new "Jails" section
- removed misleading "ZFS Volumes as Swap or Dump Devices" section
- updated shareiscsi and sharesmb option information (not supported on FreeBSD)
- replace zoned property with jailed property
zpool(8) only:
- updated device names in examples
MFC r227648:
Fix reference to fsync(2).
Add more references to SEE ALSO section.
MFC r227649:
More zfs(8) manpage fixes:
- remove shareiscsi property
- mark casesensitivity property as unsupported
- remove reference to Solaris Administration Guide
MFC r227752 (partial):
Update and desolarization of zdb(8) and zstreamdump(1) manual pages:
- synchronized to match new vendor code [1]
- removed ATTRIBUTES sections
- updated SEE ALSO sections
- properly updated copyright information (required by CDDL)
MFC r228019:
Update ZFS manual pages to a mdoc(7) reimplementation.
The zfs(8) and zpool(8) manual pages now match the state of the ZFS module
and have been customized for FreeBSD.
The new texts of the "Deduplication" subsection in zfs(8), the zpool "split"
command, the zfs "dedup" property and several other missing parts have been
added from illumos or OpenSolaris snv_134 (CDDL-licensed).
The mdoc(7) reimplementation of whole manual pages, the descriptions of the
zpool "readonly" property, "zfs diff" command and descriptions of several
other missing command flags and/or options were authored by myself.
MFC r228045:
Add missing -n flag to "zpool import" description.
MFC r228054:
Add missing warning to zfs(8) for using "zfs destroy" with -r and -R flags.
MFC r228055:
Use singular form for zfs destroy snapshot in zfs(8).
Obtained from: Illumos (as of rev. 13513:f84d4672fdbd) [1]

-.SS "ZFS File System Hierarchy"
-.sp
-.LP
-A \fBZFS\fR storage pool is a logical collection of devices that provide space for datasets. A storage pool is also the root of the \fBZFS\fR file system hierarchy.
-.sp
-.LP
-The root of the pool can be accessed as a file system, such as mounting and unmounting, taking snapshots, and setting properties. The physical storage characteristics, however, are managed by the \fBzpool\fR(1M) command.
-.sp
-.LP
-See \fBzpool\fR(1M) for more information on creating and administering pools.
-.SS "Snapshots"
-.sp
-.LP
-A snapshot is a read-only copy of a file system or volume. Snapshots can be created extremely quickly, and initially consume no additional space within the pool. As data within the active dataset changes, the snapshot consumes more data than would otherwise be shared with the active dataset.
-.sp
-.LP
-Snapshots can have arbitrary names. Snapshots of volumes can be cloned or rolled back, but cannot be accessed independently.
-.sp
-.LP
-File system snapshots can be accessed under the \fB\&.zfs/snapshot\fR directory in the root of the file system. Snapshots are automatically mounted on demand and may be unmounted at regular intervals. The visibility of the \fB\&.zfs\fR directory can be controlled by the \fBsnapdir\fR property.
-.SS "Clones"
-.sp
-.LP
-A clone is a writable volume or file system whose initial contents are the same as another dataset. As with snapshots, creating a clone is nearly instantaneous, and initially consumes no additional space.
-.sp
-.LP
-Clones can only be created from a snapshot. When a snapshot is cloned, it creates an implicit dependency between the parent and child. Even though the clone is created somewhere else in the dataset hierarchy, the original snapshot cannot be destroyed as long as a clone exists. The \fBorigin\fR property exposes this dependency, and the \fBdestroy\fR command lists any such dependencies, if they exist.
-.sp
-.LP
-The clone parent-child dependency relationship can be reversed by using the \fBpromote\fR subcommand. This causes the "origin" file system to become a clone of the specified file system, which makes it possible to destroy the file system that the clone was created from.
-.SS "Mount Points"
-.sp
-.LP
-Creating a \fBZFS\fR file system is a simple operation, so the number of file systems per system is likely to be numerous. To cope with this, \fBZFS\fR automatically manages mounting and unmounting file systems without the need to edit the \fB/etc/vfstab\fR file. All automatically managed file systems are mounted by \fBZFS\fR at boot time.
-.sp
-.LP
-By default, file systems are mounted under \fB/\fIpath\fR\fR, where \fIpath\fR is the name of the file system in the \fBZFS\fR namespace. Directories are created and destroyed as needed.
-.sp
-.LP
-A file system can also have a mount point set in the \fBmountpoint\fR property. This directory is created as needed, and \fBZFS\fR automatically mounts the file system when the \fBzfs mount -a\fR command is invoked (without editing \fB/etc/vfstab\fR). The \fBmountpoint\fR property can be inherited, so if \fBpool/home\fR has a mount point of \fB/export/stuff\fR, then \fBpool/home/user\fR automatically inherits a mount point of \fB/export/stuff/user\fR.
-.sp
-.LP
-A file system \fBmountpoint\fR property of \fBnone\fR prevents the file system from being mounted.
-.sp
-.LP
-If needed, \fBZFS\fR file systems can also be managed with traditional tools (\fBmount\fR, \fBumount\fR, \fB/etc/vfstab\fR). If a file system's mount point is set to \fBlegacy\fR, \fBZFS\fR makes no attempt to manage the file system, and the administrator is responsible for mounting and unmounting the file system.
-.SS "Zones"
-.sp
-.LP
-A \fBZFS\fR file system can be added to a non-global zone by using the \fBzonecfg\fR \fBadd fs\fR subcommand. A \fBZFS\fR file system that is added to a non-global zone must have its \fBmountpoint\fR property set to \fBlegacy\fR.
-.sp
-.LP
-The physical properties of an added file system are controlled by the global administrator. However, the zone administrator can create, modify, or destroy files within the added file system, depending on how the file system is mounted.
-.sp
-.LP
-A dataset can also be delegated to a non-global zone by using the \fBzonecfg\fR \fBadd dataset\fR subcommand. You cannot delegate a dataset to one zone and the children of the same dataset to another zone. The zone administrator can change properties of the dataset or any of its children. However, the \fBquota\fR property is controlled by the global administrator.
-.sp
-.LP
-A \fBZFS\fR volume can be added as a device to a non-global zone by using the \fBzonecfg\fR \fBadd device\fR subcommand. However, its physical properties can be modified only by the global administrator.
-.sp
-.LP
-For more information about \fBzonecfg\fR syntax, see \fBzonecfg\fR(1M).
-.sp
-.LP
-After a dataset is delegated to a non-global zone, the \fBzoned\fR property is automatically set. A zoned file system cannot be mounted in the global zone, since the zone administrator might have to set the mount point to an unacceptable value.
-.sp
-.LP
-The global administrator can forcibly clear the \fBzoned\fR property, though this should be done with extreme care. The global administrator should verify that all the mount points are acceptable before clearing the property.
-.SS "Native Properties"
-.sp
-.LP
-Properties are divided into two types, native properties and user-defined (or "user") properties. Native properties either export internal statistics or control \fBZFS\fR behavior. In addition, native properties are either editable or read-only. User properties have no effect on \fBZFS\fR behavior, but you can use them to annotate datasets in a way that is meaningful in your environment. For more information about user properties, see the "User Properties" section, below.
-.sp
-.LP
-Every dataset has a set of properties that export statistics about the dataset as well as control various behaviors. Properties are inherited from the parent unless overridden by the child. Some properties apply only to certain types of datasets (file systems, volumes, or snapshots).
-.sp
-.LP
-The values of numeric properties can be specified using human-readable suffixes (for example, \fBk\fR, \fBKB\fR, \fBM\fR, \fBGb\fR, and so forth, up to \fBZ\fR for zettabyte). The following are all valid (and equal) specifications:

+After a dataset is attached to a jail and the jailed property is set, a jailed

+.Ss Deduplication
+Deduplication is the process for removing redundant data at the block-level,
