- Some of the various things that Linux supports (such as network
- drivers, file systems, network protocols, etc.) can be in a state
- of development where the functionality, stability, or the level of
- testing is not yet high enough for general use. This is usually
- known as the "alpha-test" phase among developers. If a feature is
- currently in alpha-test, then the developers usually discourage
- uninformed widespread use of this feature by the general public to
- avoid "Why doesn't this work?" type mail messages. However, active
- testing and use of these systems is welcomed. Just be aware that it
- may not meet the normal level of reliability or it may fail to work
- in some special cases. Detailed bug reports from people familiar
- with the kernel internals are usually welcomed by the developers
- (before submitting bug reports, please read the documents
- <file:README>, <file:MAINTAINERS>, <file:REPORTING-BUGS>,
- <file:Documentation/BUG-HUNTING>, and
- <file:Documentation/oops-tracing.txt> in the kernel source).
-
- This option will also make obsoleted drivers available. These are
- drivers that have been replaced by something else, and/or are
- scheduled to be removed in a future kernel release.
-
- Unless you intend to help test and develop a feature or driver that
- falls into this category, or you have a situation that requires
- using these features, you should probably say N here, which will
- cause the configurator to present you with fewer choices. If
- you say Y here, you will be offered the choice of using features or
- drivers that are currently considered to be in the alpha-test phase.
