PKGENPACK(1) [FIXME: manual] PKGENPACK(1)NAME
pkgenpack - PackageKit Pack Generator
SYNOPSIS
pkgenpack [--help] [--verbose] [--with-package-list] [--output] [--package] [--updates]
DESCRIPTION
This manual page documents briefly the pkgenpack command.
pkgenpack is the command line client for PackageKit for creating service packs.
WHAT IS A SERVICE PACK ?
A service pack is a tarball which contains a set of packages and their dependencies. The user can reduce the dependencies to be packed
using the --with-package-list option. Along with the dependencies, a service pack has a file named metadata.conf which contains the
information about the distribution and creation date of the pack.
CREATING A SERVICE PACK ?
A service pack is created using the command pkgenpack.
OPTIONS
This program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included
below.
--help
Show summary of options.
--verbose
Show extra debugging information.
--with-package-list
Set the filename of dependencies to be excluded.
Generally, the file list of packages is generated when doing a PackageKit refresh on the target system. If not specified, pkgenpack
uses /var/lib/PackageKit/system.package-list by default.
--output
The directory to put the pack file, or the current directory if omitted.
--package
The package to be put into the ServicePack.
--update
Put all updates available in the ServicePack.
NAMING A SERVICE PACK
The only valid extension for a service pack is ".servicepack".
EXAMPLES
1. Tim is facing problems with his Internet connection at home. He needs a service pack with valgrind and it's dependencies for his system.
He asks James to generate a pack for him. Both know James's system should contain similar packages as Tim's system, as both of them have
installed Fedora 9 two days ago.
James simply runs:
[james@jamesbook:~]$ pkgenpack --output=/media/USB/TimPacks --package=valgrind
This generates a file /media/USB/TimPacks/valgrind-fedora-9-i686.servicepack on the USB key Tim gave to James. Tim can now go home, insert
the USB key and double clicks on the valgrind-fedora-9-i686.servicepack file to be prompted to install these packages.
2. Bill wants to create a service pack named kdegames-fedora-9-i686.servicepack for his new system which does not have an internet
connection. He generates a list of packages on his system using pkcon list-create and copies that list to his USB key. He then gives that
USB to Rishi who has a good internet connectivity. Rishi runs the following command on his system:
[rishi@devils-temple:~]$ pkgenpack --with-package-list=/media/USB/bill.package-list
--output=/home/rishi/Desktop --program=kdegames
This generates a service pack, kdegames-fedora-9-i686.servicepack, on Rishi's Desktop, which can be distributed to Bill and users with
similar requirements.
INSTALLING A SERVICE PACK
Service Packs can be installed using pkcon. For example:
[hacker@tim-lounge:~]$ pkcon install /media/USB/TimPacks/valgrind-fedora-9-i686.servicepack
