BOM(5) — UNIX Programmer’s Manual
NAME
bom − Bill of materials
DESCRIPTION
BuildDisk, Installer, and the software provided for upgrading to a new release of NEXTSTEP all use a file system “bill of materials” to determine which files to install, remove, or upgrade. A bill of materials (BOM) is similar to the output of “ls -lR”; it lists all the files that a directory contains, along with some information about each file: the file’s UNIX permissions, its owner and group, its size, its time of last modification, and so on. Also included are a checksum for each file and information about hard links.
A BOM file (named with the suffix “.bom”) stores the bill of materials for a single directory in a binary format. Since NEXTSTEP includes a number of optional packages which may or may not be installed on a particular computer, more than one BOM file may be needed to characterize a given NEXTSTEP installation.
The bill of materials for a minimal NEXTSTEP system is stored in /usr/lib/NextStep/BaseSystem.bom. BOMs for optional packages are found within the package receipts located in /NextLibrary/Receipts. For example, the bill of materials for the NEXTSTEP Documentation package is located in /NextLibrary/Receipts/Documentation.pkg/Documentation.bom.
FILES
/usr/lib/NextStep/BaseSystem.bom − BOM for the non-optional parts of NEXTSTEP
/NextLibrary/Receipts/∗.pkg/∗.bom − BOMs for other installed packages
