.A service pack is a tarball which contains a set of packages and their dependencies. To explain better what a service pack is, it is best to show a few use-cases.
You can add multiple packages to a service pack by separating the package names with a comma, for instance hal,gnome-power-manager.
- You have seven desktops you've just installed with Fedora 9. Each one needs to have 204Mb of updates installed.
- You have a laptop that needs network drivers before it can download updates, and you have a similar up to date laptop with internet access nearby. The network drivers require a few dependencies, and other packages to be upgraded before they will install.
- You frequently install Linux on other peoples computers. You carry around a live-cd and a pendrive with a single 204Mb file Fedora-updates-SP1.servicepack which contains all the updates since last week.
- A free software magazine wants to distribute patent encumbered multimedia plugins and programs with the latest Fedora release DVD. They want a way in which even the most lazy user can get the things installed without much fuss.
Internally, the pack file is just an uncompressed tarball, with the packages and a single metadata.conf file inside. The metadata file is just the distribution identifier and the time of creation. This ensures you don't try installing a fedora-9-i386 service pack on a ubuntu-intrepid-ppc machine.
We need a destination file list because we not know what packages are installed on the destination computer. For example:

Computer A has the following packages installed, and has internet access.
- glib
- dbus
- dbus-glib
- libgnome
Computer B has the following packages installed, and does not have internet access.
- glib
- dbus
- kdebase
- kdeapps
O equipo B quere ter un «Service pack» que conteña unha versión máis nova de k3b para poder gravar DVD-RW.
The k3b program has dependancies of dbus, dbus-glib and kdebase. Now, if we asked computer A to download k3b, it would download k3b and kdebase but not dbus-glib. We need to provide computer A with the information about what packages computer B has got installed before we can create the service pack.
If we generate a package list on computer B, and the transfer it to computer A on a USB pendrive or CDRW we can download the correct packages. In this case we would download k3b and dbus-glib and pack it into the new service pack.
Agora pode transferir o «Service pack» do equipo A ao equipo B nun soporte USB.
The pkgenpack command line tool can also be used for creating service pack files.
