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-DESTROY 8
Remove hard coded "Linux" OS from manpages The recommended practice for `.Os` on FreeBSD is to not specify any arguments. The correct OS name is used automatically. Oddly enough, on the Linux distro I tested this on (CentOS 7), the man pager defaulted to displaying "BSD" as the OS rather than "Linux". To accommodate this, tack " Linux" back on in an install hook on Linux. This is much simpler than removing it for FreeBSD when vendored in the base system.

.Sh EXAMPLES
.\" These are, respectively, examples 3, 10, 15 from zfs.8
.\" Make sure to update them bidirectionally
.Ss Example 1 : No Creating and Destroying Multiple Snapshots
The following command creates snapshots named
.Ar yesterday No of Ar pool/home
and all of its descendent file systems.
Each snapshot is mounted on demand in the
.Pa .zfs/snapshot
directory at the root of its file system.
The second command destroys the newly created snapshots.
.Dl # Nm zfs Cm snapshot Fl r Ar pool/home Ns @ Ns Ar yesterday
.Dl # Nm zfs Cm destroy Fl r Ar pool/home Ns @ Ns Ar yesterday
.
.Ss Example 2 : No Promoting a ZFS Clone
The following commands illustrate how to test out changes to a file system, and
then replace the original file system with the changed one, using clones, clone
promotion, and renaming:
.Bd -literal -compact -offset Ds
.No # Nm zfs Cm create Ar pool/project/production
populate /pool/project/production with data
.No # Nm zfs Cm snapshot Ar pool/project/production Ns @ Ns Ar today
.No # Nm zfs Cm clone Ar pool/project/production@today pool/project/beta
make changes to /pool/project/beta and test them
.No # Nm zfs Cm promote Ar pool/project/beta
.No # Nm zfs Cm rename Ar pool/project/production pool/project/legacy
.No # Nm zfs Cm rename Ar pool/project/beta pool/project/production
once the legacy version is no longer needed, it can be destroyed
.No # Nm zfs Cm destroy Ar pool/project/legacy
.Ed
.
.Ss Example 3 : No Performing a Rolling Snapshot
The following example shows how to maintain a history of snapshots with a
consistent naming scheme.
To keep a week's worth of snapshots, the user destroys the oldest snapshot,
renames the remaining snapshots, and then creates a new snapshot, as follows:
.Bd -literal -compact -offset Ds
.No # Nm zfs Cm destroy Fl r Ar pool/users@7daysago
.No # Nm zfs Cm rename Fl r Ar pool/users@6daysago No @ Ns Ar 7daysago
.No # Nm zfs Cm rename Fl r Ar pool/users@5daysago No @ Ns Ar 6daysago
.No # Nm zfs Cm rename Fl r Ar pool/users@4daysago No @ Ns Ar 5daysago
.No # Nm zfs Cm rename Fl r Ar pool/users@3daysago No @ Ns Ar 4daysago
.No # Nm zfs Cm rename Fl r Ar pool/users@2daysago No @ Ns Ar 3daysago
.No # Nm zfs Cm rename Fl r Ar pool/users@yesterday No @ Ns Ar 2daysago
