A macro distribution is a term I coined.&nbsp;&nbsp;It implies a software
distribution larger than a mini distribution usually

base distribution which provides the foundation to create a full size
distribution.&nbsp;&nbsp;It is usually pruned, and provides the
absolute minimum needed to provide all the functionality usually
associated with a full sized distribution, yet it still uses the same
libraries and binaries.&nbsp;&nbsp;Because it can be made quickly, it is
useful for creating a current snapshot of ones own host systems, and can be
used to run experiments safely without fear of corrupting the host system

Genext2fs is used. This progam allows a normal user to create an ext2
filesystem with all uids and gids belonging to 0 (root) without the need for
a loop or ram device.&nbsp;&nbsp;Device nodes are created from a device table
file written to by gbootroot.&nbsp&nbsp;This program is authored by
Xavier Bestel, but the version used by gbootroot has
modifications from Erik Andersen (BusyBox) to allow a device table
to be used rather than a device listing.&nbsp;&nbsp;The maximum allowable size
for a filesystem is 8192k.&nbsp;&nbsp;User and group information
can be changed when the filesystem is run from a kernel.

<b>What is make_debian, and how do I use it?</b></p>
<p>
Make_debian is a script which takes information from
a Debian installation and creates a template which can be used to make a
macro distribution using gBootRoot's yard method.&nbsp;&nbsp;
It creates replacements for important configuration files to represent
the actual packaging state it will be providing.&nbsp;&nbsp;
In order to use this script you need to be running a Debian-like
distribution, anotherwards, one which uses dpkg, apt and file-rc to maintain
its packaging and boot hierarchy.&nbsp;&nbsp;Dswim is used to collect
information used in making the template.&nbsp;&nbsp;You will need to build the
filesystem as root because it exceeds the 8192k limit provided by genext2fs.</p>
<p>
Run make_debian from the command-line.&nbsp;&nbsp;The script first finds all
required packages on your host system, then it checks to see if any of
the extra packages mentioned in its configuration are missing.&nbsp;&nbsp;
As a rule, even if extra packages
are missing, a working distribution will still be created.&nbsp;&nbsp;
The script will then ask you a few questions,
and then proceed to make Debian-`uname -n`.yard in your template
directory.&nbsp;&nbsp;
<p>
<em>Extra Packages and static template data:</em>
<br>
You can resolve missing packages by installing them on your system, or you can
edit the script and replace these packages with a suitable replacement,
since you may be using a different version of Debian then the author
used when putting together make_debian.&nbsp;&nbsp;Make a copy of make_debian,
and then edit the part under EDIT HERE between qw().&nbsp;&nbsp;
You may edit the static data in the template from
within the script below where it is clearly marked as editable.
While on the subject the <b>make-debian-x11 add-on</b> is actually the
result of
making these modifications.&nbsp;&nbsp;First, extra packages were
added, second, extra replacements were provided and the static information
in the template was modified to reflect these replacements.
