-.Sh NAME
-.Nm disklabel
-.Nd disk pack label
-.Sh SYNOPSIS
-.Fd #include <sys/disklabel.h>
-.Sh DESCRIPTION
-Each disk or disk pack on a system may contain a disk label
-which provides detailed information
-about the geometry of the disk and the partitions into which the disk
-is divided.
-It should be initialized when the disk is formatted,
-and may be changed later with the
-.Xr disklabel 8
-program.
-This information is used by the system disk driver and by the bootstrap
-program to determine how to program the drive
-and where to find the filesystems on the disk partitions.
-Additional information is used by the filesystem in order
-to use the disk most efficiently and to locate important filesystem information.
-The description of each partition contains an identifier for the partition
-type (standard filesystem, swap area, etc.).
-The filesystem updates the in-core copy of the label if it contains
-incomplete information about the filesystem.
-.Pp
-The label is located in sector number
-.Dv LABELSECTOR
-of the drive, usually sector 0 where it may be found
-without any information about the disk geometry.
-It is at an offset
-.Dv LABELOFFSET
-from the beginning of the sector, to allow room for the initial bootstrap.
-The disk sector containing the label is normally made read-only
-so that it is not accidentally overwritten by pack-to-pack copies
-or swap operations;
-the
-.Dv DIOCWLABEL
-.Xr ioctl 2 ,
-which is done as needed by the
-.Xr disklabel
-program.
-.Pp
-A copy of the in-core label for a disk can be obtained with the
-.Dv DIOCGDINFO
-.Xr ioctl ;
-this works with a file descriptor for a block or character (``raw'') device
-for any partition of the disk.
-The in-core copy of the label is set by the 
-.Dv DIOCSDINFO
-.Xr ioctl .
-The offset of a partition cannot generally be changed while it is open,
-nor can it be made smaller while it is open.
-One exception is that any change is allowed if no label was found
-on the disk, and the driver was able to construct only a skeletal label
-without partition information.
-Finally, the 
-.Dv DIOCWDINFO
-.Xr ioctl
-operation sets the in-core label and then updates the on-disk label;
-there must be an existing label on the disk for this operation to succeed.
-Thus, the initial label for a disk or disk pack must be installed
-by writing to the raw disk.
-All of these operations are normally done using
-.Xr disklabel .
-.Pp
-The format of the disk label, as specified in
-.Aw Pa sys/disklabel.h ,
-is
-.Bd -literal
