The directory system described in the previous chapter is itself
contained within <em>distribution directories</em>. Each

To summarize, the Debian archive has a root directory within an FTP
server. For instance, at the mirror site,
contained in <ftppath>/debian</ftppath>, which is a common location
(another is <ftppath>/pub/debian</ftppath>).
<p>
-Within that archive root, the actual distributions are contained in
-the <tt>dists</tt> directory. Here is an overview of the layout:
- <p>
-<example>
-<var>archive root</var>/dists/<var>distribution</var>/<var>section</var>/<var>architecture</var>/<var>subsection</var>/<var>packages</var>
-</example>
+A distribution is comprised of Debian source and binary packages, and the
+respective <tt>Sources</tt> and <tt>Packages</tt> index files, containing
+the header information from all those packages. The former are kept in the
+<tt>pool/</tt> directory, while the latter are kept in the <tt>dists/</tt>
+directory of the archive (because of backwards compatibility).
-Extrapolating from this layout, you know that to find the i386 base

There is always a distribution called <em>stable</em> (residing in

+Packages get copied from <em>unstable</em> to <em>testing</em> if they

+as soon as anything it depends on is also added. This process is automatic.
+ <p>
+After a period of development, once the release manager deems fit, the

<p>
The <em>experimental</em> distribution is a specialty distribution.
It is not a full distribution in the same sense as `stable' and
Every released Debian distribution has a <em>code name</em>: Debian
1.1 is called `buzz'; Debian 1.2, `rex'; Debian 1.3, `bo'; Debian 2.0,
`hamm'; Debian 2.1, `slink'; and Debian 2.2, `potato'. There is also
-a ``pseudo-distribution'', called `sid', which is contains packages for
-architectures which are not yet officially supported or released by
-Debian. These architectures are planned to be integrated into the
-mainstream distribution at some future date.
+a ``pseudo-distribution'', called `sid', which is the current
+`unstable' distribution; since packages are moved from `unstable' to
+`testing' as they approach stability, `sid' itself is never released.
+As well as the usual contents of a Debian distribution, `sid' contains
+packages for architectures which are not yet officially supported or
+released by Debian. These architectures are planned to be integrated
+into the mainstream distribution at some future date.
<p>
Since Debian has an open development model (i.e., everyone can
-participate and follow the development) even the unstable distribution
-is distributed to the Internet through the Debian FTP and HTTP server
-network. Thus, if we had called the directory which contains the
-development version `unstable', then we would have to rename it to
-`stable' when the version is released, which would cause all FTP
-mirrors to re-retrieve the whole distribution (which is quite
-large).

want to get a bug-fix release into <em>frozen</em>, you would set the
distribution to `frozen unstable'. (See <ref id="upload-frozen"> for
more information on when to upload to <em>frozen</em>.) Note that it
never makes sense to combine the <em>experimental</em> distribution with
-anything else. Also note that setting the distribution to `stable' means

+You should avoid combining `stable' with others because of potential
