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.
