pkgmap is an ASCII file that provides a complete listing of the package contents. It is automatically generated by pkgmk(1) using the information in the prototype(4) file.
Each entry in pkgmap describes a single ``deliverable object file.'' A deliverable object file includes shell scripts, executable objects, data files, directories, and so forth.
The entry consists of several fields of information, each field separated by a space. The fields are described below and must appear in the order shown.
-
part
- An optional field designating the part number in which the object resides. A part
is a collection of files and is the atomic unit by which a package is processed. A developer can choose the criteria for grouping files into a part (for example, based on class). If no value is defined
in this field, part 1 is assumed.
-
ftype
- A one-character field that indicates the file type. Valid values are:
- b
- block special device
- c
- character special device
- d
- directory
- e
- a file to be edited upon installation or removal (may be shared by several packages)
- f
- a standard executable or data file
- i
- installation script or information file
- l
- linked file
- p
- named pipe
- s
- symbolic link
- v
- volatile file (one whose contents are expected to change, like a log file)
- x
- an exclusive directory accessible only by this package
-
class
- The installation class to which the file belongs. This name must contain only alphanumeric characters and be no longer
than 12 characters. It is not specified if the ftype is i (information file).
-
pathname
-
pathname may contain variables of the form $variable
that support install-time configuration of the file. variable may be embedded in the pathname structure. (See prototype(4) for definitions of variable specifications.)
Do not use the following reserved words in pathname, since they are applied by pkgadd(1M) using a different mechanism:
| |
PKG_INSTALL_ROOT
BASEDIR
CLIENT_BASEDIR
|
-
major
- The major device number. The field is only specified for block or character special devices.
-
minor
- The minor device number. The field is only specified for block or character special devices.
-
mode
- The octal mode of the file (for example, 0664). A question mark (?) indicates that the mode will be
left unchanged, implying that the file already exists on the target machine. This field is not used for linked files, packaging information files, or non-installable files.
The mode can contain a variable specification. (See prototype(4) for definitions
of variable specifications.)
-
owner
- The owner of the file (for example, bin or root). The field is limited to 14 characters
in length. A question mark (?) indicates that the owner will be left unchanged, implying that the file already exists on the target machine. This field is not used for linked files or
non-installable files. It is used optionally with a package information file. If used, it indicates with what owner an installation script will be executed.
The owner can contain a variable specification. (See prototype(4) for definitions
of variable specifications.)
-
group
- The group to which the file belongs (for example, "bin" or "sys"). The field is limited to 14 characters in length.
A question mark (?) indicates that the group will be left unchanged, implying that the file already exists on the target machine. This field is not used for linked files or non-installable
files. It is used optionally with a package information file. If used, it indicates with what group an installation script will be executed.
The group can contain a variable specification. (See prototype(4) for definitions
of variable specifications.)
-
size
- The actual size of the file in bytes. This field is not specified for named pipes, special devices, directories or linked
files.
-
cksum
- The checksum of the file contents. This field is not specified for named pipes, special devices, directories, or linked
files.
-
modtime
- The time of last modification, as reported by the stat(2) function call. This field is not specified for named pipes, special devices, directories, or linked files.
Each pkgmap file must have one line that provides information about the number of parts, maximum size of parts that make up the package, and, optionally, the size of the package
after compression (where size is given in 512-byte blocks). This line is in the following format:
: number_of_parts maximum_part_size compressed_pkg_size
Lines that begin with ``#'' are comment lines and are ignored.
When files are saved during installation before they are overwritten, they are normally just copied to a temporary pathname. However, for files whose mode includes execute permission (but which are
not editable), the existing version is linked to a temporary pathname and the original file is removed. This allows processes which are executing during installation to be overwritten.
