The current Abitti 1 version runs on Debian Linux. The end-of-life of the underlying DigabiOS distribution will happen after the test days in spring 2026.
In Digabi 1, test takers start their laptops from USB sticks and the servers run in a similar fashion. You can run the server as VirtualBox VM. For this, we have an end-user helper application, Naksu.
While Debian GNU/Linux is itself based on open source, the Abitti exam system is not. Also, the disk image contains 3rd party software with separate licenses. All end-user licenses and the record of processing activities can be found at Abitti.fi.
If you are providing applications to Abitti 1 you might want to take a look at the instructions how to tinker Digabi 1 (DigabiOS).
- The client distribution runs on candidates’ devices
- The server distribution runs on exam arrangers’ devices
For documentation, see doc/*.md. Manual for live-build toolset:
Debian Live Manual.
To get an overview of the building process see doc/building.md. However, while this repository contains the code required to build the kernel and the image the complete Abitti image contains packages from various sources.
DigabiOS is not an open source project. The DigabiOS contains binary packages from various sources:
- DigabiOS uses GNU/Linux kernel obtained from Debian source packages. The source kernels are as-is except a one-line patch that disables booting with an arbitrary initrd. The patched kernel sources can be found at https://static.abitti.fi/kernel-sources/index.html.
- Most of the binary files in the image are unchanged Debian packages. The package owning a file can be queried using the standard Debian tool
dpkg. The sources of these unchanged packages are provided by the Debian project. The sources of changed GPL licensed packages can be found at https://static.abitti.fi/patched-sources/index.html. - The DigabiOS contains closed source software. The MEB has signed license agreements with the respective parties and further gives Abitti users rights mentioned in the Abitti license agreement.
- The Abitti exam system, which in this case means code showing the exam questions, material and recording the test takers’ submissions is owned by the MEB. It is licensed according to the aforementioned Abitti license agreement. Some modules are open source, see https://abitti.net.
The source code is released here on grounds of transparency. The maintainers of the repository do not actively investigate pull request or issues. To contact MEB regarding this repository, please use the address abitti@ylioppilastutkinto.fi.
