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 file.
Each entry in pkgmap describes a single ``deliverable object file.'' A
deliverable object file includes shell scripts, executable objects, data
files, directories, etc. 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 (e.g., 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:
f a standard executable or data file
e a file to be edited upon installation or removal
v volatile file (one whose contents are expected to
change)
d directory
x an exclusive directory
l linked file
p named pipe
c character special device
b block special device
i installation script or information file
s symbolic link
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 The pathname where the object will reside on the target
machine, such as /usr/bin/mail. Relative pathnames (those that
do not begin with a slash) indicate that the file is
relocatable.
For linked files (ftype is either l or s), pathname must be in
the form of path1=path2, with path1 specifying the destination
of the link and path2 specifying the source of the link.

For symbolically linked files, path2 can be a relative
pathname, such as ./ or ../. For example, if you enter a line
such as
s /foo/bar/etc/mount=../usr/sbin/mount
path2 (/foo/bar/etc/mount) will be a symbolic link to
../usr/sbin/mount.
pathname may contain variables which support relocation of the
file. A $parameter may be embedded in the pathname structure.
$BASEDIR can be used to identify the parent directories of the
path hierarchy, making the entire package easily relocatable.
Default values for parameter and BASEDIR must be supplied in
the pkginfo file and may be overridden at installation.
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.
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.
Can be a variable specification in the form of $[A-Z]. Will be
resolved at installation time.
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.
Can be a variable assignment in the form of $[A-Z]. Will be
resolved at installation time.

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 must have one line that provides information about the number
and maximum size (in 512-byte blocks) of parts that make up the package.
This line is in the following format:
:number_of_parts maximum_part_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.
