15.5 Creating Images

If the image description is complete (for further information about the image
description tree structure, refer to Section
sponding cash register image and the boot image can be generated using the
imageBuilder (image.pl) and the SLRS installation CDs and are stored as de-
scribed in Section 15.4.
With the exception of the boot image, all the images are based on a reduced
SUSE Minimal System (no YaST packages). The primary process that takes
place during the generation of an cash register image is implemented as fol-
lows:
1. Read out global the imageBuilder configuration file:
/etc/opt/SLES/POS/AdminServer.conf
The file structure has the Key=Value format. The following information
from this file is used:
SLESCD[n]
The SLESCD[n] parameter describes where the SUSE Linux instal-
lation CD number [n] is located. This information is used to initial-
ize the package subdirectory.
2. Check signature for all the packages listed in setup.
3. Set logging level.
4. Build the root structure from the basic structure of the files directory.
All the required binaries and libraries are extracted from the respective
packages. At this point, the image version as defined by the image to
generate is also written to /etc/ImageVersion.
5. Initialize the RPM database.
6. Read the configuration file setup and install the indicated packages for
this image.
7. Check the installation for dependencies.
8. Run the setup scripts from the script directory to remove unneeded files.
9. Copy the files and directories of the files-user structure into the image.
10. Run the optional configuration script config.system, if present.
