From ab9848aa9b0c115092bac9321db43fea887a5a7c Mon Sep 17 00:00:00 2001 From: Warner Losh Date: Thu, 6 Feb 2020 17:52:02 +0000 Subject: [PATCH] No need to make sunlabel anymore It was only built on sparc64. Since it wasn't a general tool on other architectures, no need to keep it around for another release.

SUNLABEL 8 -.Os -.Sh NAME -.Nm sunlabel -.Nd read and write disk pack label suitable for Sun's OpenBoot PROM -.Sh SYNOPSIS -.Nm -.Op Fl r -.Op Fl c No \&| Fl h -.Ar disk -.Nm -.Fl B -.Op Fl b Ar boot1 -.Op Fl n -.Ar disk -.Nm -.Fl R -.Op Fl B Op Fl b Ar boot1 -.Op Fl r -.Op Fl n -.Op Fl c -.Ar disk protofile -.Nm -.Fl e -.Op Fl B Op Fl b Ar boot1 -.Op Fl r -.Op Fl n -.Op Fl c -.Ar disk -.Nm -.Fl w -.Op Fl B Op Fl b Ar boot1 -.Op Fl r -.Op Fl n -.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 FILES -.Bl -tag -width ".Pa /boot/boot1" -compact -.It Pa /boot/boot1 -Default boot image. -.El -.Sh SEE ALSO -.Xr vi 1 , -.Xr geom 4 , -.Xr bsdlabel 8 -.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. diff --git a/sbin/sunlabel/sunlabel.c b/sbin/sunlabel/sunlabel.c deleted file mode 100644 index
