pkg_create [-OZhv] [-P dpkgs] [-C cpkgs] [-e emulation] [-p prefix] [-i iscript] [-k dscript] [-r rscript] [-s fake-prefix] [-S fake-base] [-t template] [-X excludefile] [-D displayfile] [-m mtreefile] -c comment -d description -f packlist pkg-name
The pkg_create command is used to create packages that will subsequently be fed to one of the package extraction/info utilities. The input description and command line arguments for the creation of a package are not really meant to be human-generated, though it is easy enough to do so. It is more expected that you will use a front-end tool for the job rather than muddling through it yourself. Nonetheless, a short descrip- tion of the input syntax is included in this document. The options are as follows: -f packinglist Fetch "packing list" for package from the file packinglist or stdin if packinglist is a dash "-". -c [-]desc Fetch package "one line description" from file desc or, if pre- ceded by "-", the argument itself. This string should also give some idea of which version of the product (if any) the package represents. -d [-]desc Fetch long description for package from file desc or, if preceded by "-", the argument itself. -Y Assume a default answer of "Yes" for any questions asked. -N Assume a default answer of "No" for any questions asked. -O Go into a "packing list only" mode. This is used to do "fake pkg_add" operations when a package is installed. In such cases, it is necessary to know what the final, adjusted packing list will look like. -v Turn on verbose output. -h Force tar to follow symbolic links, so that the files they point to are dumped, rather than the links themselves. -i iscript Set iscript to be the install procedure for the package. This can be any executable program (or shell script). It will be invoked automatically when the package is later installed. -P dpkgs Set the initial package dependency list to dpkgs. This is assumed to be a whitespace separated list of package names and is meant as a convenient shorthand for specifying multiple @pkgdep direc- tives in the packing list (see PACKING LIST DETAILS section below). -C cpkgs Set the initial package conflict list to cpkgs. This is assumed to be a whitespace separated list of package names and is meant as a convenient shorthand for specifying multiple @pkgcfl direc- tives in the packing list (see PACKING LIST DETAILS section below). -e emulation Set the initial list of required binary emulations to emulation. This should be a whitespace separated list of emulations and is meant as a shorthand to specifying one or more @emul directives in the packing list. -p prefix Set prefix as the initial directory "base" to start from in selecting files for the package, and to record as the base for installing the package. -s fake-prefix Set fake-prefix as the real initial directory to start from in selecting files for the package. -S fake-base Set fake-base as the prefix to prepend to any file to select for the package. -k dscript Set dscript to be the de-install procedure for the package. This can be any executable program (or shell script). It will be in- voked automatically when the package is later (if ever) de- installed. -r rscript Set rscript to be the "requirements" procedure for the package. This can be any executable program (or shell script). It will be invoked automatically at installation/deinstallation time to determine whether or not installation/deinstallation should proceed. -t template Use template as the input to mkstemp(3). By default, this is the string /tmp/instmp.XXXXXX, but it may be necessary to override it in the situation where space in your /tmp directory is limited. Be sure to leave some number of "X" characters for mkstemp(3) to fill in with a unique ID. -X excludefile Pass excludefile as a --exclude-from argument to tar when creat- ing final package. See tar man page (or run tar with --help flag) for further information on using this flag. -D displayfile Display the file (using more(1)) after installing the package. Useful for things like legal notices on almost-free software, etc. -m mtreefile Run mtree(8) with input from mtreefile before the package is in- stalled. mtree is invoked as mtree -u -f mtreefile -d -e -p prefix, where prefix is the name of the first directory named by a @cwd directive. -Z Do not try to create SV4CPIO archives.
The "packing list" format (see -f) is fairly simple, being nothing more than a single column of filenames to include in the package. Directories (with a trailing slash) can also be added. They are then created at in- stallation time and deleted in reverse order upon package deletion. However, since absolute pathnames are generally a bad idea for a package that could be installed potentially anywhere, there is another method of specifying where things are supposed to go and, optionally, what owner- ship and mode information they should be installed with. This is done by embedding specialized command sequences in the packing list. Briefly described, these sequences are: @cwd directory Set the internal directory pointer to point to directory. All subsequent filenames will be assumed relative to this directory. @src directory Set the internal directory pointer for creation only to directory. That is to say that it overrides @cwd for package creation but not extraction. @emul Binary emulation (kernel personality) the software needs. Only necessary for binary-only software. If several binary emulations are needed, each of them needs to be in a separate @emul command. @arch, @endfake Ignored, only exist for the sake of compatibility. @ldcache value Specifies whether ldconfig will be called for the directories that contain libraries (@lib directives). value should be 0 on static architectures, 1 otherwise. Deprecated, use @option ldcache et al instead. @info filename Special version of the file entry for GNU info files. Automati- cally includes chapter files (filename-*) and runs install-info(1) as needed. @man filename Special version of the file entry for manpages. For now, no differences to a normal file entry. @shell filename Special version of the file entry for shell binaries. For now, no differences to a normal file entry. @lib filename Special version of the file entry for shared libraries. Automati- cally adds ldconfig calls at installation and deinstallation time if they are missing. @exec command Execute command as part of the unpacking process. If command con- tains any of the following sequences somewhere in it, they will be expanded inline. For the following examples, assume that @cwd is set to /usr/local and the last extracted file was bin/emacs. %F Expands to the last filename extracted (as specified); in the example case, bin/emacs. %D Expands to the current directory prefix, as set with @cwd; in the example case /usr/local. %B Expands to the "basename" of the fully qualified filename, that is the current directory prefix, plus the last filespec, minus the trailing filename. In the exam- ple case, that would be /usr/local/bin. %f Expands to the "filename" part of the fully qualified name, or the converse of %B; in the example case, emacs. @unexec command Execute command as part of the deinstallation process. Expansion of special % sequences is the same as for @exec. This command is not executed during the package add, as @exec is, but rather when the package is deleted. This is useful for deleting links and other ancillary files that were created as a result of adding the package, but not directly known to the package's table of con- tents (and hence not automatically removable). The advantage of using @unexec over a deinstallation script is that you can use the "special sequence expansion" to get at files regardless of where they've been potentially redirected (see -p). @mode mode Set default permission for all subsequently extracted files to mode. Format is the same as that used by the chmod command (well, considering that it's later handed off to it, that's no surprise). Use without an arg to set back to default (extraction) permissions. @owner user Set default ownership for all subsequently extracted files to user. Use without an arg to set back to default (extraction) own- ership. @group group Set default group ownership for all subsequently extracted files to group. Use without an arg to set back to default (extraction) group ownership. @comment string Imbed a comment in the packing list. Useful in trying to document some particularly hairy sequence that may trip someone up later. @ignore Used internally to tell extraction to ignore the next file (don't copy it anywhere), as it's used for some special purpose. @name name Set the name of the package. This is mandatory and is usually put at the top. This name is potentially different than the name of the file it came in, and is used when keeping track of the pack- age for later deinstallation. Note that pkg_create will derive this field from the package name and add it automatically if none is given. @dirrm name Declare directory name to be deleted at deinstall time. By de- fault, directories created by a package installation are not deleted when the package is deinstalled; this provides an expli- cit directory cleanup method. This directive should appear at the end of the package list. If more than one @dirrm directive is used, the directories are removed in the order specified. The name directory will not be removed unless it is empty. If several packages reference the same directory, it will only be removed after the last of those packages has been removed. @extra file Declare extra file file to be deleted at deinstall time, if user sets -c option. Those files are extra configuration files that are normally not deleted. If file ends with a slash, it is a directory. @extraunexec command Extra command to execute when removing extra files. @sample filename The preceding file entry is a sample configuration file. It is copied to filename at pkg_add(1) time if filename does not al- ready exist. If it exists and is different from the sample, a warning is printed. If filename ends with a slash, it specifies a directory to be created instead. At pkg_delete(1) time, the entry is treated like @extra, i.e. it is only deleted if the -c option is given to pkg_add. @mtree name Declare name as an mtree(8) input file to be used at install time (see -m above). Only the first @mtree directive is honored. @display name Declare name as the file to be displayed at install time (see -D above). @pkgdep pkgname Declare a dependency on the pkgname package. The pkgname package must be installed before this package may be installed, and this package must be deinstalled before the pkgname package is dein- stalled. Multiple @pkgdep directives may be used if the package depends on multiple other packages. @pkgcfl pkgcflname Declare a conflict to the pkgcflname package. The pkgcflname package must not be installed if pkgname package gets installed because they install the same files and thus conflict. pkgcflname may use fnmatch(3) wildcards, csh-style alternates or the opera- tors <, <=, >, and >=. As an example for the latter, subversion<1.4 and subversion-<1.4.0-0 are equivalent. @option name Effects vary depending on name. no-default-conflict By default, a package conflicts with other versions of the same package. With this option, the older package version will still be noticed, but the installation will proceed anyway. base-package This is a base package, i.e. one that is so important that removing it will almost certainly break the system (for example the pkgtools package). Base packages can only be removed using the -f option to pkg_delete(1). dylib Enable support for Darwin-style shared libraries. Shared library names (@lib) are automatically converted into dylib names. The links are also automatically added. gnu-ld Enable support for GNU-style shared libraries, needed for example under Interix. Automatically adds the library links to the packing list and execute ldconfig according- ly. ldcache Support for "OpenBSD-style" shared libraries. Automati- cally execute ldconfig for the shared library directories during install and uninstall. static Don't support shared libraries. This is the default if none of the other options are given.
pkg_add(1), pkg_delete(1), pkg_info(1), sysconf(3)
The pkg_create command first appeared in FreeBSD.
Jordan Hubbard most of the work John Kohl refined it for NetBSD Thorsten Glaser MirOS adaptions. Benny Siegert Effort to make the MirOS package tools compatible to the new perlish OpenBSD package tools by Marc Espie.
Hard links between files in a distribution must be bracketed by @cwd directives in order to be preserved as hard links when the package is ex- tracted. They additionally must not end up being split between tar invo- cations due to exec argument-space limitations (this depends on the value returned by sysconf(_SC_ARG_MAX)). Sure to be others.
Since MirOS #8, a patched paxtar is necessary because pkg_create creates SysV4 CPIO archives with CRC by default, instead of POSIX ustar archives. Use the -Z parameter to prevent pkg_create from adding -S to tar(1). This version is mostly compatible with the new OpenBSD package tools. Some of the new keywords are unsupported and will result in an error mes- sage from pkg_create. Using pathnames which contain spaces is unsupported. MirOS BSD #10-current November 22, 2009 5
