12.6 Packaging the Sample Implementation

The LSB-si is released in several configurations for each of the following architectures:

  1. Base system A tarball containing only what is required by the LSB Written Specification. Can be entered via chroot. For complete conformance, requires the underlyingLinux kernel to be LSB-conformant.

  2. Testable system Contains the base system plus additional files and programs needed to enable the LSB-si as a testing environment. This bundle can run the LSB Runtime test suite and LSB-conformant applications. Can be entered via chroot. Once running, it is possible to telnet into the environment. Complete conformance requires the underlying Linux kernel to be LSB-conformant.

  3. Bootable system The files from the base system plus a kernel and other support to make it possible to boot a standalone. Some additional configuration will be necessary—for example, an appropriate boot configuration for the target hardware and configuration of necessary kernel modules.

  4. Hosted system The files from the base system plus support to run User-Mode Linux, a kernel virtual machine that runs as a user-level application on the host system. User-Mode Linux may not be available for all LSB-supported architectures. The hosted bundle is also available as an installable, ready-to-run package.


When the package is being extended beyond the base, there's a tradeoff: The system becomes more usable, but includes various non-LSB commands and files, and therefore is a little less "pure" in a testing sense.
