3.8. Training systems
Requirements
[ug] In training departments, computers that are provided for training participants (including
pupils/students) must frequently be reset.
Solution
[ug] The training systems are implemented by automatically installed zones:
• Sparse-root zones, that is, the zones inherit everything possible from the global zone.
• Automatic zone creation per script.
• Automatic system configuration in the zone with sysidcfg.
• Automatic IP address administration.
• Option: /opt is not inherited (inherit-pkg-dir), for installation training.
• Option: Automatic quick installation of a zone.
• Option: Application administrator with root access.
• Option: Installation of shared software per mount
Assessment
[ug] This use case has the following characteristics:
• Operating the training computers is extremely simple since zones can easily be created again
for the next course.
• Training participants themselves are root in the zone, which allows them to perform all essential
administrative functions without posing a hazard to the total system. Re-installation of the
computer is thus not necessary.
• The trainer can see the work of the training participants from the global zone.
• The costs for the training system therefore decrease drastically.
