The creation of custom POS operating system images for cash registers is
based on image description trees, which are provided with the SLRS along
with prebuilt POS CR images. An image description contains all the files in a
directory that are required to generate a cash register image using the Perl-
based imageBuilder image.pl. Aside from the image.pl script, the command
line tool scr (setup cash register) is also provided. The usage of the scr is
shown below.
The path /opt/SLES/POS/system is selected as the source path for the image
description directory. The directory to which the description files are written
must include a three-part version number in its name in the format:
ImageName-Major.Minor.Release
For smaller image modifications that do not add or remove any new
packages, only the release number is incremented. The config and setup
files remain unchanged.
