-.Op Fl r

-.Op Fl c
-.Ar disk type
-.Sh DESCRIPTION
-The
-.Nm
-utility
-installs, examines or modifies the
-.Em Sun OpenBoot PROM
-label on a disk.
-In addition,
-.Nm
-can install bootstrap code.
-.Ss Introduction
-The label occupies the first sector (i.e., 512 bytes) of each disk.
-It starts with a textual description which by convention also mentions
-the disk geometry in textual form (number of cylinders, alternate
-cylinders, heads, and sectors per track), optionally followed by a
-table of SVR4-compatible VTOC tags and flags per partition, followed
-by the partition table itself.
-Finally, a checksum is recorded to ensure the label has not been
-tampered with.
-.Pp
-The
-.Em Sun OpenBoot PROM
-label allows for 8 disk partitions.
-The partition table lists the starting cylinder of the partition,
-plus the size of the partition in 512-byte sectors.
-Thus, partitions in the
-.Em Sun OpenBoot PROM
-must always start at a cylinder boundary (for whatever geometry
-emulation has been chosen).
-.Pp
-The optional SVR4-compatible VTOC tag and flags table is not used
-by the
-.Fx
-kernel.
-It is maintained solely for compatibility with the
-.Tn Solaris
-operating system that might share disks with
-.Fx
-on the same hardware platform.
-.Pp
-The
-.Em Sun OpenBoot PROM
-label is natively understood by the underlying hardware, which can
-bootstrap from a single partition entry, as opposed to the very first
-block(s) of the entire disk as on many other hardware platforms.
-.Pp
-Note that the hardware platform mandates that two cylinders are set
-aside as
-.Em alternate cylinders
-which are not available to user programs (and not even through the
-.Dq Li backup
-partition).
-.Ss Options
-Options are listed in alphabetical order here.
-Note that only those option combinations listed under
-.Sx SYNOPSIS
-are allowable.
-.Bl -tag -width ".Fl b Ar bootpath"
-.It Fl b Ar bootpath
-Specify that
-.Ar bootpath
-is to be used as the boot image, rather than the default of
-.Pa /boot/boot1 .
-.It Fl B
-Install bootstrap code onto the disk.
-Note that since the underlying hardware platform bootstraps from
-partitions, not disks, this operation is only useful if there is
-a partition starting at offset 0.
-.It Fl c
-Use cylinders for partition size display rather than
-(512-byte) sectors.
-This also changes the default interpretation of the partition
-size entries when editing the label, or reading from a prototype
-file.
-Thus, prototype files are only compatible when both, obtaining
-the file and re-installing it is done using the same
-.Fl c
-option setting.
-.It Fl e
-Enter edit mode.
-See
-.Sx Edit mode
-below for a more detailed explanation.
-.It Fl h
-When displaying the label, make the partition size and offset
-values
-.Dq human readable .
-The displayed numbers will get a suffix of
-.Ql B
-for bytes,
-.Ql K
-for 1024 bytes each,
-.Ql M
-for 1048576 bytes each, or
-.Ql G
-for 1073741824 bytes each appended.
-Note that due to possible rounding errors, prototype files
-obtained using the
-.Fl h
-option are not suited for re-installing using the
-.Fl R
-option.
-.It Fl n
-No changes.
-All operations, checks etc., are performed normally, but nothing
-is written to disk.
-.It Fl r
-Obsolete option that used to indicate that the operation should
-be done directly on disk, as opposed through the respective kernel
-services.
-Ignored.
-.It Fl R
-Restore label from the prototype in
-.Ar protofile .
-A prototype file is simply the textual representation of the
-label as printed using the first form of the
-.Nm
-utility shown in the
-.Sx SYNOPSIS .
-Note that the
-.Fl c
-option used to obtain the prototype must match the option used
-when restoring the label (both present, or both absent).
-.It Fl w
-Write mode.
-Suitable to write an initial label to disk.
-The
-.Ar type
-argument used to be an entry into a table of predefined labels,
-but this functionality is not supported by
-.Nm .
-Instead, the only allowable
-.Ar type
-argument is the string
-.Dq Li auto ,
-indicating that an automatically created label should be written
-to disk.
-This automatism will try to create an initial label that fits as
-best as possible into the available disk capacity.
-.El
-.Pp
-If neither of the
-.Fl e , R ,
-or
-.Fl w
-options are present, the existing label for
-.Ar disk
-will be printed to standard output.
-.Pp
-The
-.Ar disk
-argument
-must be given as a plain disk name, without any leading
-.Pa /dev/ .
-.Ss Edit mode
-In edit mode, the existing label from
-.Ar disk
-will be read, and put into a template file.
-The command referenced by the
-.Ev EDITOR
-environmental variable will be started to allow the user
-to edit the label.
-The label is then checked and examined for any errors.
-If no errors have been found, the new label is written to disk.
-If there were any errors, a message is printed to standard
-error output, and the user is given the opportunity to edit
-the template file again.
-If accepted, editing starts over.
-If declined, no changes will
-be written to disk.
-.Pp
-The label presented for editing is the same as the standard
-printout, with some added hints about the possible options to
-specify the sector size and starting cylinder.
-The following areas in the template can be edited:
-.Bl -tag -width indent
-.It Sy Textual label, geometry emulation
-The line
-.D1 Li text: Ar XXXX Li cyl Ar CC Li alt 2 hd Ar HH Li sec Ar SS
-represents the label text.
-It must be retained exactly in the form shown.
-The editable text
-.Ar XXXX
-is a simple (non-whitespace) text describing the disk.
-By convention, this text mentions the approximate size of the
-disk, as in
-.Dq Li SUN9.0G
-for a 9 GB disk shipped by Sun.
-.Pp
-The values
-.Ar CC ,
-.Ar HH ,
-and
-.Ar SS
-describe the number of cylinders, heads (tracks per
-cylinder), and sectors per track respectively.
-They might be modified to change the geometry emulation.
-Each number must be between 1 and 65535.
-The product
-.D1 Em (CC + 2) * HH * SS
-must be less than or equal to the total number of sectors of the
-disk (which is given as a hint in a comment field).
-.It Sy Volume name
-The volume name (if present) is introduced by the string
-.Dq "volume name:" .
-It can be up to 8 characters long, and might be useful to distinguish
-different disks in a system.
-Note that volume names require the VTOC elements to be present, so
-any of the VTOC constraints described below need to be obeyed as well
-if a volume name is to be set.
-Setting an empty volume name will delete it from the label.
-.It Sy Partition entries
-Partition entries start with a letter from
-.Ql a
-through
-.Ql h ,
-immediately followed by a colon, followed by the size of this
-partition, and the starting cylinder of the partition.
-The unit of the size field defaults to sectors, or to cylinders
-if the
-.Fl c
-option is in effect.
-Alternatively, a different unit may be specified by appending
-.Ql s
-for (512-byte) sectors,
-.Ql c
-for cylinders,
-.Ql k
-for kilobytes,
-.Ql m
-for megabytes, or
-.Ql g
-for gigabytes.
-The last partition entry may specify the size as
-.Ql *
-to indicate that this entry should consume the rest of disk not
-consumed by any other partition so far.
-.Pp
-The start of partition is always taken as a cylinder number (starting
-at 0) since this is what the underlying hardware uses.
-Alternatively, specifying it as
-.Ql *
-will make the computation automatically chose the nearest possible
-cylinder boundary.
-.Pp
-Partition
-.Ql c
-must always be present, must start at 0, and must cover the entire
-disk (without considering the alternate cylinders though).
-.Pp
-Optionally, each partition entry may be followed by an SVR4-compatible
-VTOC tag name, and a flag description.
-The following VTOC tag names are known:
-.Bl -column -offset indent ".Li unassigned" ".Sy value" ".Sy comment"
-.It Sy name Ta Sy value Ta Sy comment
-.It Li unassigned Ta No 0x00 Ta \&
-.It Li boot Ta No 0x01 Ta \&
-.It Li root Ta No 0x02 Ta \&
-.It Li swap Ta No 0x03 Ta \&
-.It Li usr Ta No 0x04 Ta \&
-.It Li backup Ta No 0x05 Ta c partition, entire disk
-.It Li stand Ta No 0x06 Ta \&
-.It Li var Ta No 0x07 Ta \&
-.It Li home Ta No 0x08 Ta \&
-.It Li altsctr Ta No 0x09 Ta alternate sector partition
-.It Li cache Ta No 0x0a Ta Solaris cachefs partition
-.It Li VxVM_pub Ta No 0x0e Ta VxVM public region
-.It Li VxVM_priv Ta No 0x0f Ta VxVM private region
-.El
-.Pp
-The following VTOC flags are known:
-.Bl -column -offset indent ".Sy name" ".Sy value" ".Sy comment"
-.It Sy name Ta Sy value Ta Sy comment
-.It Li wm Ta No 0x00 Ta read/write, mountable
-.It Li wu Ta No 0x01 Ta read/write, unmountable
-.It Li rm Ta No 0x10 Ta read/only, mountable
-.It Li ru Ta No 0x11 Ta read/only, unmountable
-.El
-.Pp
-Optionally, both the tag and/or the flag name may be specified
-numerically, using standard
-.Ql C
-numerical notation (prefix
-.Ql 0x
-for hexadecimal numbers,
-.Ql 0
-for octal numbers).
-If the flag field is omitted, it defaults to
-.Ql wm .
-If the tag field is also omitted, it defaults to
-.Dq Li unassigned .
-If none of the partitions lists any VTOC tag/flags, no
-SVR4-compatible VTOC elements will be written to disk.
-If VTOC-style elements are present, partition
-.Ql c
-must be marked as
-.Dq Li backup
-(and should be marked
-.Ql wu ) .
-.El
-.Pp
-When checking the label, partition
-.Ql c
-is checked for presence, and for the mentioned restrictions.
-All other partitions are checked for possible overlaps, as
-well as for not extending past the end of unit.
-If VTOC-style elements are present, overlaps of unmountable
-partitions against other partitions will be warned still but
-do not cause a rejection of the label.
-That way,
-.Em encapsulated disks
-of volume management software are acceptable as long as the
-volume management partitions are clearly marked as unmountable.
-.Pp
-Any other fields in the label template are informational only,
-and will not be parsed when reading the label.
-.Pp
-Note that when changing the geometry emulation by editing the
-textual description line, all partition entries will be
-considered based on the new geometry emulation.
-.Sh ENVIRONMENT
-.Bl -tag -width ".Ev EDITOR" -compact
-.It Ev EDITOR
-Name of the command to edit the template file in edit-mode.
-Defaults to
-.Xr vi 1 .
-.El

-.Sh HISTORY
-The
-.Nm
-utility appeared in
-.Fx 5.1 .
-.Sh AUTHORS
-The
-.Nm
-utility was written by
-.An Jake Burkholder ,
-modeling it after the
-.Xr bsdlabel 8
-command available on other architectures.
-.Pp
-.An -nosplit
-This man page was initially written by
-.An David O'Brien ,
-and later substantially updated by
-.An J\(:org Wunsch .
-.Sh BUGS
-Installing bootstrap code onto an entire disk is merely pointless.
-.Nm
-should rather support installing bootstrap code into a partition
-instead.
-.Pp
-The
-.Dq auto
-layout algorithm could be smarter.
-By now, it tends to emulate fairly large cylinders which due to
-the two reserved alternate cylinders causes a fair amount of
-wasted disk space.
