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.

.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.
