Linux on Mobile Devices
16.2.1 Basic Terminology and Concepts
The following are some terms used in SCPM documentation and in the
YaST module.
The term system configuration refers to the complete configuration of
the computer. It covers all fundamental settings, like use of partitions,
network settings, time zone selection, and keyboard mappings.
A profile, also called configuration profile, is a state that has been pre-
served and can be restored at any time.
Active profile refers to the profile last selected. This does not mean that
the current system configuration corresponds exactly to this profile,
because the configuration can be customized at any time.
A resource in the SCPM context is an element that contributes to the
system configuration. This can be a file or a softlink including its
metadata, like user, permissions, or access time. This can also be a
system service that runs in this profile, but is deactivated in another
one.
Every resource belongs to a certain resource group. These groups con-
tain all resources that logically belong together — most groups would
contain both a service and its configuration files. It is very easy to as-
semble resources managed by SCPM because this does not require
any knowledge about the configuration files of the desired service.
SCPM ships with a selection of preconfigured resource groups that
should be sufficient for most scenarios.
16.2.2 SCPM YaST Module and Additional
Documentation
The YaST module (package yast2-profile-manager) is a graphical
front-end to SCPM that provides an alternative to the command line front-
end. Because the functionality of both front-ends is substantially the same
and knowledge of the command line front-end is useful in many cases,
only the latter is described here. Differences between the YaST front-end
and the command line tool are mentioned wherever appropriate.
Refer to the info pages of SCPM for the most recent documentation.
Read these with tools like Konqueror (with the command konqueror
info:scpm) or emacs. On the console, use info or pinfo. Technical in-
formation is provided at /usr/share/doc/package/scpm. Running
scpm without any arguments returns a command option summary.
