You can install one Aegir Master Instance on your server using
Barracuda and any number of Aegir Satellite Instances using
Octopus installer.

Note: the 'Master' and 'Satellite' names in the Barracuda/Octopus
context are not related to the multi-server Aegir features.
It is related to the multi-Aegir-instances environment, with
virtual chroot/jail for every Aegir instance.

Barracuda is the main script for the Aegir Master Instance system
install and upgrades, including OS env and main Aegir instance,
but no platforms will be added there to keep it compatible
with all existing and future installs, when you don't need
any ready to use platforms and instead you are using the system
for managing your own imported platforms/sites.

Octopus is an Aegir + Platforms installer (you can interactively
choose the platforms you wish to install on the instance)
and updater only. It allows to install new versions of platforms
with clean directory structure, with code shared between all created
instances, so one vanilla Octopus instance is using only ~18 MB,
while most of the code, which is over 1700 MB total, is shared.

Sharing the code between instances is of critical importance,
because it allows you to dramatically lower RAM and CPU usage,
because most of the actively used code is opcode cached with APC.

With multi-install system you have to remember that all of them
will use the same Nginx server, so you could break the system
trying to install site with the same domain on two or more instances.
The instances will not be aware of other running instances,
so it is your responsibility to use such system wisely.

There is also Tuner script available (see aegir/tools/BOND.sh.txt)
for easy system tuning for development and switching it back easily
to the standard production settings.

### OCTOPUS PLATFORMS

Octopus can install the platforms listed below:

 Acquia 6.27.1 (int) ---------- http://bit.ly/acquiadrupal

 CiviCRM 4.1.6-d6 ------------- http://civicrm.org

 Conference 1.0-rc2 ----------- http://usecod.com
 Drupal 7.18.1 ---------------- http://drupal.org/drupal-7.18
 Drupal 8.0-dev-tested -------- http://bit.ly/drupal-eight
 ELMS 1.0-beta1 --------------- http://elms.psu.edu
 Feature Server 1.1 ----------- http://bit.ly/fserver

 NodeStream 1.5.1 ------------- http://nodestream.org
 NodeStream 2.0-beta8 --------- http://nodestream.org

 Open Outreach 1.0-rc7 -------- http://openoutreach.org
 OpenChurch 1.11-beta7 -------- http://openchurchsite.com
 OpenPublish 3.0-beta7 -------- http://openpublishapp.com
 OpenScholar 2.0-rc1 ---------- http://openscholar.harvard.edu
 Panopoly 1.0-rc3 ------------- http://drupal.org/project/panopoly
 Pressflow 5.23 --------------- http://pressflow.org
 Pressflow 6.27.1 (int) ------- http://pressflow.org
 ProsePoint 0.45 -------------- http://prosepoint.org
 Ubercart 2.11.1 (int) -------- http://ubercart.org
 Ubercart 3.3.1 --------------- http://ubercart.org

There are also platforms temporarily disabled for new installs,
because they are either outdated, with numerous security updates
not applied by maintainer, or sometimes no longer possible to use
with Drush based install because of fatal errors, or even abandoned
with no development for months and no issues fixed in the meantime.

Note that we still support some semi-abandoned distros listed above,
but at some point we may no longer be able to maintain their security
and version updates, and they may be moved to the second list below.

We also removed D8-edge platform, since it is broken too often
because of D8 own critical bugs. We will keep debugging it to add
latest D8-tested platform to every release.

The platforms listed below can be re-added when their maintainers
will fix all critical issues and/or apply required updates:

 MartPlug --------------------- http://drupal.org/project/martplug
 Octopus Video ---------------- http://octopusvideo.org
 Open Academy ----------------- http://drupal.org/project/openacademy
 Open Enterprise -------------- http://drupal.org/project/openenterprise
 OpenPublic ------------------- http://openpublicapp.com
 Videola ---------------------- http://videola.tv

All D5/D6 platforms have been enhanced using Pressflow Drupal core.

All D7 platforms include some hotfixes published between latest
Drupal core release and latest BOA release.

Platforms marked with (int) come also with ready to use translations
of Drupal core in 25 languages. Only languages with at least
10 maintainers and at least 60% of progress are included.
Other platforms are using extended and customized translations or
require far more than just core translation, so we don't touch them.

There are also some useful and/or performance related modules
added to all 6.x and 7.x platforms.

Some core and contrib modules are either enabled or disabled
by default, by running daily (at morning) maintenance monitor.

There are also modules supported by Octopus, but not bundled
by default and/or not enabled.

Some modules require custom rewrites on the web server level,
but since there is no .htaccess available/used in Nginx,
we have added all required rewrites and associated supported
configuration settings on the system level. This is the real
meaning of [S]upported flag here.

Note that while some of them are enabled by default on initial
install of "blank" site in the supported platform, they are
not forced as enabled by the running daily maintenance monitor,
so we marked them as [S]oft[E]nabled.

Here is a complete list with corresponding flags for every
module/theme: [S]upported, [B]undled, [F]orce[E]nabled,
[S]oft[E]nabled or [F]orce[D]isabled. [NA] means that
this module is used without the need to enable it.

Supported core version is listed for every module or theme
as [D6] and/or [D7].
