Describes the format of a package contents description file.
The pkgmap file is an ASCII file that provides a complete listing of the package contents. Each entry in pkgmap describes a single "deliverable object file." A deliverable object file includes shell scripts, executable objects, data files, and directories. 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.
| Field | Description |
|---|---|
| part | A 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:
Once a file has the file type attribute v, it will always be volatile. For example, if a file being installed already exists and has the file type attribute v, then even if the version of the file being installed is not specified as volatile, the file type attribute remains volatile. |
| 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 resides 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, when path2 is a relative pathname starting with ./ or ../, path2 is not considered relocatable. For example, if you enter a line such as s /foo/bar/etc/mount=../usr/sbin/mount path1 (/foo/bar/etc/mount) is a symbolic link to ../usr/sbin/mount. pathname can contain variables which support relocation of the file. A "$"parameter can 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 can be overridden at installation. Special characters, such as an equal sign ("="), are included in pathnames by surrounding the entire pathname in single quotes (as in, for example, '/usr/lib/~='). |
| 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 is 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 is 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
is executed.
The owner can be a variable specification in the form of $[A-Z] and is 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 is 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 is executed.
Can be a variable assignment in the form of $[A-Z] and is 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. This field is not specified for named pipes, special devices, directories, or linked files. |
The following three optional fields must be used as a group. That is, all three must be specified if any is specified.
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.
The pkgmap file can contain only one entry per unique pathname.
An exclusive directory type (file) type x specifies directories that are constrained to contain only files that appear in the installation software database (/var/sadm/install/contents). If there are other files in the directory, they are removed by pkgchk -fx as described on the manual page for the pkgchk command.
Variable specifications for the owner and group fields are defined in the pkginfo file. For example, owner could be $OWNER in the pkgmap file; if OWNER is defined as root in the pkginfo file, $OWNER gets the value root when the file is installed.
The following is an example pkgmap file.
