Add gpart(8).

Browse Source 
In order to support gpart(8), geom(8) needs to support a named
argument. Also, optional string parameters are a requirement.
Both have been added to the infrastructure. The former required
all existing classes to be adjusted.

.Dt GPART 8
.Os
.Sh NAME
.Nm gpart
.Nd "control utility for the disk partitioning GEOM class"
.Sh SYNOPSIS
To add support for the disk partitioning GEOM class,
place one or more of the following
lines in your kernel configuration file:
.Bd -ragged -offset indent
.Cd "options GEOM_PART_APM"
.Cd "options GEOM_PART_GPT"
.Ed
.Pp
The GEOM_PART_APM option adds support for the Apple Partition Map (APM)
found on Apple Macintosh computers, and the GEOM_PART_GPT option adds
support for the GUID Partition Table (GPT) found on Intel Itanium
computers and Intel-based Macintosh computers.
.Pp
Usage of the
.Xr gpart 8
utility:
.Pp
.\" ==== ADD ====
.Nm
.Cm add
.Fl b Ar start
.Fl s Ar size
.Fl t Ar type
.Op Fl i Ar index
.Op Fl l Ar label
.Op Fl f Ar flags
.Ar geom
.\" ==== COMMIT ====
.Nm
.Cm commit
.Ar geom
.\" ==== CREATE ====
.Nm
.Cm create
.Fl s Ar scheme
.Op Fl n Ar entries
.Op Fl f Ar flags
.Ar provider
.\" ==== DELETE ====
.Nm
.Cm delete
.Fl i Ar index
.Op Fl f Ar flags
.Ar geom
.\" ==== DESTROY ====
.Nm
.Cm destroy
.Op Fl f Ar flags
.Ar geom
.\" ==== MODIFY ====
.Nm
.Cm modify
.Fl i Ar index
.Op Fl l Ar label
.Op Fl t Ar type
.Op Fl f Ar flags
.Ar geom
.\" ==== UNDO ====
.Nm
.Cm undo
.Ar geom
.\"
.Sh DESCRIPTION
The
.Nm
utility is used to partition GEOM providers, normally disks.
The first argument of which is the action to be taken:
.Bl -tag -width ".Cm wwwwwww"
.\" ==== ADD ====
.It Cm add
Add a new partition to the partitioning scheme given by
.Ar geom .
The partition begins on the logical block address given by the
.Fl b Ar start
option.
Its size is expressed in logical block numbers and given by the
.Fl s Ar size
option.
The type of the partition is given by the
.Fl t Ar type
option.
Partition types are discussed in the section entitled "Partition Types".
.Pp
Addition options include:
.Bl -tag -width ".Fl w Ar wwwwwww"
.It Fl i Ar index
The index in the partition table at which the new partition is to be
placed. The index determines the name of the device special file used
to represent the partition.
.It Fl l Ar label
The label attached to the partition.
This option is only valid when used on partitioning schemes that support
partition labels.
.It Fl f Ar flags
Additional operational flags.
See the section entitled "Operational flags" below for a discussion
about its use.
.El
.\" ==== COMMIT ====
.It Cm commit
Commit any pending changes for geom
.Ar geom .
All actions are being committed by default and will not result in
pending changes.
Actions can be modified with the
.Fl f Ar flags
option so that they are not being committed by default.
As such, they become pending.
Pending changes are reflected by the geom and the
.Nm
utility, but they are not actually written to disk.
The
.Cm commit
action will write any and all pending changes to disk.
.\" ==== CREATE ====
.It Cm create
Create a new partitioning scheme on a provider given by
.Ar provider .
The
.Fl s Ar scheme
option determines the scheme to use.
The kernel needs to have support for a particular scheme before
that scheme can be used to partition a disk.
.Pp
Addition options include:
.Bl -tag -width ".Fl w Ar wwwwwww"
.It Fl n Ar entries
The number of entries in the partition table.
Every partitioning scheme has a minimum and a maximum number of entries
and this option allows tables to be created with the number of entries
that lies anywhere between the minimum and the maximum.
Some schemes have a maximum equal to the minimum and some schemes have
a maximum large enough to be considered unlimited.
By default, partition tables are created with the minimum number of
entries.
.It Fl f Ar flags
Additional operational flags.
See the section entitled "Operational flags" below for a discussion
about its use.
.El
.\" ==== DELETE ====
.It Cm delete
Delete a partition from geom
.Ar geom
and further identified by the
.Fl i Ar index
option.
The partition cannot be actively used by the kernel.
.Pp
Addition options include:
.Bl -tag -width ".Fl w Ar wwwwwww"
.It Fl f Ar flags
Additional operational flags.
See the section entitled "Operational flags" below for a discussion
about its use.
.El
.\" ==== DESTROY ====
.It Cm destroy
Destroy the partitioning scheme as implemented by geom
.Ar geom .
.Pp
Addition options include:
.Bl -tag -width ".Fl w Ar wwwwwww"
.It Fl f Ar flags
Additional operational flags.
See the section entitled "Operational flags" below for a discussion
about its use.
.El
.\" ==== MODIFY ====
.It Cm modify
Modify a partition from geom
.Ar geom
and further identified by the
.Fl i Ar index
option.
Only the the type and/or label of the partition can be modified.
To change the type of a partition, specify the new type with the
.Fl t Ar type
option.
To change the label of a partition, specify the new label with the
.Fl l Ar label
option.
Not all partitioning schemes support labels and it is invalid to
try to change a partition label in such cases.
.Pp
Addition options include:
.Bl -tag -width ".Fl w Ar wwwwwww"
.It Fl f Ar flags
Additional operational flags.
See the section entitled "Operational flags" below for a discussion
about its use.
.El
.\" ==== UNDO ====
.It Cm undo
Revert any pending changes.
This action is the opposite of the
.Cm commit
action and can be used to undo any changes that have not been committed.

.Sh PARTITION TYPES
The
.Nm
utility uses symbolic names for common partition types to avoid that the
user needs to know what the partitioning scheme in question is and what
the actual number or identification needs to be used for a particular
type.
the
.Nm
utility also allows the user to specify scheme-specific partition types
for partition types that don't have symbol names.
The symbolic names currently understood are:
.Bl -tag -width "wwwwwwwwwwwww"
.It efi
The system partition for computers that use the Extensible Firmware
Interface (EFI).
In such cases, the GPT partitioning scheme is being used and the
actual partition type for the system partition can also be specified as
"!c12a7328-f81f-11d2-ba4b-00a0c93ec93ab".
.It freebsd
A FreeBSD partition that uses the BSD disklabel to sub-divide the
partition into file systems.
This is a legacy partition type and should not be used for the APM
or GPT schemes.
The scheme-specific types are "!FreeBSD" for APM, and
"!516e7cb4-6ecf-11d6-8ff8-00022d09712b" for GPT.
.It freebsd-swap
A FreeBSD partition dedicated to swap space.
The scheme-specific types are "!FreeBSD-swap" for APM, and
"!516e7cb5-6ecf-11d6-8ff8-00022d09712b" for GPT.
.It freebsd-ufs
A FreeBSD partition that contains a UFS or UFS2 file system.
the scheme-specific types are "!FreeBSD-UFS" for APM, and
"!516e7cb6-6ecf-11d6-8ff8-00022d09712b" for GPT.
.It freebsd-vinum
A FreeBSD partition that contains a Vinum volume.
The scheme-specific types are "!FreeBSD-Vinum" for APM, and
"!516e7cb8-6ecf-11d6-8ff8-00022d09712b" for GPT.
.It mbr
A partition that is sub-partitioned by a master boot record (MBR).
This type is known as "!024dee41-33e7-11d3-9d69-0008c781f39f" by GPT.
.El
.Sh OPERATIONAL FLAGS
Actions other than the
.Cm commit
and
.Cm undo
actions take an optional
.Fl f Ar flags
option.
This option is used to specify action-specific operational flags.
By default, the
.Nm
utility defines the 'C' flag so that the action is immediately
committed.
The user can specify
.Fl f Ar x
to have the action result in a pending change that can later, with
other pending changes, be committed as a single compound change with
the
.Cm commit
action or reverted with the
.Cm undo
action.
.Sh EXIT STATUS
Exit status is 0 on success, and 1 if the command fails.
.Sh SEE ALSO

.Xr geom 8 ,
.Sh HISTORY

.Nm
utility appeared in
