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 (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:

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. 

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. 

EXAMPLES

The following is an example of a pkgmap file.
