Ross Williams 870fc32fc9 Reorganize zfs(8) man page into sections
Most subcommands got their own manpages (e.g. create). Some related
commands grouped into a single manpage and symlinks created (e.g. set, 
get, and inherit). I did this when topics were either too short to 
warrant their own file or so interrelated that a user would want to
refer between commands in the same file.

Corrected .Sx internal references to .Xr cross refs; lots of .Sx 
references from when text was all in zfs.8 needed to be changed to 
.Xr zfs-$SUBCOMMAND 8 cross references.

Divided subcommand list in zfs(8) into sections of related 
functionality. This required writing new descriptions for some 
commands.

Preserved ".Os Linux", `.Os` macro parsing behavior differs between 
mandoc from the "BSD" mandoc package (available on Ubuntu) and man 
from Ubuntu's man-db package, which calls groff to format the manpages.

Groff handles the `.Os` macro differently and wrongly, defaulting 
it to "BSD" in `/usr/share/groff/*/tmac/mdoc/doc-common`, instead of
getting the default from `uname`.

A future set of changes will introduce build-time preprocessing of
manpages for platform-specific documentation and can insert the
correct operating system name.

Added SEE ALSO sections, the newly-divided zfs-*.8 subcommand man
pages needed their own SEE ALSO sections pointing to related
subcommands and, in some cases, documentation from other packages
(e.g. zfs-share.8).

.Dt ZFS-PROMOTE 8
.Os Linux
.Sh NAME
.Nm zfs Ns Pf - Cm promote
.Nd Promotes a clone file system to no longer be dependent on its origin snapshot.
.Sh SYNOPSIS
.Nm
.Cm promote
.Ar clone-filesystem
.Sh DESCRIPTION
.Bl -tag -width ""
.It Xo
.Nm
.Cm promote
.Ar clone-filesystem
.Xc
The
.Cm promote
command makes it possible to destroy the file system that the clone was created
from.
The clone parent-child dependency relationship is reversed, so that the origin
file system becomes a clone of the specified file system.
.Pp
The snapshot that was cloned, and any snapshots previous to this snapshot, are
now owned by the promoted clone.
The space they use moves from the origin file system to the promoted clone, so
enough space must be available to accommodate these snapshots.
No new space is consumed by this operation, but the space accounting is
adjusted.
The promoted clone must not have any conflicting snapshot names of its own.
The
.Xr zfs-rename 8
subcommand can be used to rename any conflicting snapshots.
