NAME

pkgmap - package contents description file

DESCRIPTION

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(5) 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 listed below. File types are divided between
those that are not to be modified and those that are
modifiable.

Files of the following types must never be modified:

b
block special device


c
character special device


d
directory


f
a standard executable file, data file, or other type
of file, the contents of which must never be
modified.


i
information file (such as a file containing a
copyright, list of dependencies, or package
information) or installation script (such as
checkinstall, class action [i.], pre/post
install/remove), the contents of which must never be
modified.


l
linked file


p
named pipe


s
symbolic link


x
an exclusive directory accessible only by this
package

Files of the following types can be modified:

e
An editable file, intended to be edited (selectively
modified) after installation. An editable file is
expected to change on installation or removal, can
be shared by several packages, and must be installed
by a class action script. Examples are a
configuration file or a list of users.


v
A volatile file, intended to be overwritten or
appended to after installation. A volatile file is
not expected to change on installation or removal,
is not preserved between installations, and can be
installed by a class action script. Examples are a
log file or a lock file.

Following package installation, the contents of files of
all types except e and v must not change. Any file that
is subject to change should be marked as e or v.


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(5) for definitions of variable specifications.)

Do not use the following reserved words in pathname,
since they are applied by pkgadd(8) 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(5) 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
or changed to the owner stored in the package database,
which could be different from what is on the file system.
When the question mark is used, it implies that the file
is already on the file system. 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(5) 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 or changed to the owner stored in the package
database, which could be different from what is on the
file system. When the question mark is used, it implies
that the file is already on the file system. 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(5) 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.
