+ <title>Bring it to the community</title>
+ <para>
+ One of the best ways of justifying a decision to reject a patch
+ and working to not seem like you keep an iron grip on your
+ project is by not making the decision alone at all. It might
+ make sense to turn over larger proposed changes or more
+ difficult decisions to a development mailing list where they can
+ be discussed. There will be some patches (bug fixes, etc.) which
+ will definitely be accepted and some that you feel are so off
+ base that they do not even merit further discussion. It is those
+ that fall into the grey area between these two groups that might
+ merit a quick forward to a mailing list.

+ effort of working with the developer submitting the patch to iron out bugs and
+ incorporate the change if you thing you think it seems like a

+ The most common way of branching your project is to have one
+ branch that is stable and one that is development. This is the
+ model followed by the Linux kernel that is described in <xref
+ linkend="chooseversioning">. In this model, there is always one
+ branch that is stable and always one that is in
+ development. Before any new release, the development branch goes
+ into a <quote>feature freeze</quote> where major changes and added
+ features are rejected or put on hold under the development kernel
+ is released as the new stable branch and major development begins
+ again on the development branch. Bug fixes and small changes that
+ are unlikely to have any large negative repercussions are

+ available but has expanded to this to include: stable, unstable,
+ testing, experimental, and (around release time) a frozen
+ distribution that only incorporates bug fixes during the
+ transition from unstable to stable. There are few projects whose

+ <quote>stable,</quote> <quote>unstable</quote> and
+ <quote>frozen</quote> to point to which ever distribution (by
+ name) is in whatever stage. Both methods work and their are
+ others. In any case, it is important that different branches

- A: Linux can run just fine on one drive (spindle). Having

- A: There is only a minor snag: if even a single partition

+ <title>Bug management software</title>
<para>
- Q: OK, so should I split the system into as many partitions as
- possible for a single drive?
+ For many large software projects, use of bug management software
+ is essential to keep track of which bugs have been fixed, which
+ bugs have not been fixed, and which bugs are being fixed by
+ which people. Debian uses the <ulink
+ url="http://bugs.debian.org">Debian Bug Tracking System</ulink>
+ (<acronym>BTS</acronym>) although it may not be best choice for
+ every project (it seems to currently be buckling under its own
+ weight. As well as a damn good web browser, the mozilla project
+ has spawned a sub-project resulting in a bug tracking system
+ called <ulink
+ url="http://www.mozilla.org/projects/bugzilla/">bugzilla</ulink>.
</para>
<para>
- A: No, there are several disadvantages to that. First of all
- maintenance becomes needlessly complex and you gain very little
- in this. In fact if your partitions are too big you will seek
- across larger areas than needed. This is a balance and
- dependent on the number of physical drives you have.
+ These systems (and others like them) can be unwieldy so
+ developers should be careful to not spend more time on the bug
+ tracking system than on the bugs or the projects themselves. If
+ a project continues to grow, use of a bug tracking system can
+ provide an easy standard way for users and testers to report
+ bugs and for developers and maintainers to fix them in an
+ orderly fashion.
