PAIPIX new release 7, based on debina-live.

[Antonio.Amorim at sim.fc.ul.pt (Antonio Amorim)]

Dear Colleagues,

I have just published PAIPIX 7 (http://www.paipix.org) that is using 
debian-live. PAIPIX is main focused on scientific applications.
Clearly it was only possible due to the excellence of the work of the 
debian-live team. Thanks!

There are some main concepts that I have added to the debian-live:
1- The Debian-live image only has about one third of the packages. The 
Debian repository that goes with the DVD includes not only include the 
image packages but also all other ones that can then be installed either 
live or in an installed system (see PAIPIX menu or paipix-install command).

2- To achieve this the system runs apt-cdrom when booted live.
Have a look at the scripts/i386/chroot_local-hooks/install.sh for the 
actual work.

The source code for all PAIPIX packages is available from the paipix 
repository, together with the compiled versions. The patches to the 
live-helper package are available in the paipix-helper package.

use: deb http://mirror.paipix.org/debian-paipix etch main contrib non-free
apt-get install paipix-helper and have a look at 
/usr/share/doc/paipix-helper (/changes) for all the scripts and 
coorrections that I have applyed to debian-live. They are applyed to 
live-helper_1.0~a22-1_all.deb that was checked out form svn.

Patches include avoiding the unionfs problems in /proc/self/exe that are 
important for example to the SUN java packages.

Please feel free to ask if you have any further question and once again 
thank you for developing the excellent live-helper,

Ant?nio Amorim

PS: I include bellow the general announcement:

PAIPIX 7 the new integrated PAIPIX

The new PAIPIX 7 GNU/Linux keeps its focus on scientific software but 
drops the emphasis on a pure live DVD to integrate, in the same DVD, the 
installation, live and upgrade systems.

These solutions result form using the Debian official packages 
debian-live and debian-cd, making the development of PAIPIX more 
sustainable in the medium range. The new main use cases are:

LIVE: Starting PAIPIX in the live mode, one has access to complete 
system including KDE, Office and Development. In a second stage, the 
PAIPIX menu allows to install in memory all remaining applications. This 
approach is usable since a typical live session only explores a 
restricted subset of applications. It still allows you to try all the 
available software without installing it definitely it in the hard disk.

INSTALLATION: By starting PAIPIX in the installation mode one has access 
to the standard debian-installer system. The installer was configured 
(pre-seeded) to reproduce the complete KDE, Office and Development 
environment available in the live system with further access to all 
packages trough the PAIPIX installation menu. The DVD includes all 
binary packages necessary to the full system installation.

UPGRADE: As part of the entire system, the DVD includes a Debian-CDROM 
like repository that includes all necessary packages. This repository 
can be also be used to upgrade or install further packages in any Debian 
type installation. To upgrade an existing system one should use the 
apt-cdrom add command to add this DVD to the list of used repositories.

The PAIPIX iso images are available in English (PAIPIX) and in bilingual 
editions that support both English and one of the following languages: 
Portuguese (PAIPIX-PT), Spanish (PAIPIX-ES), French (PAIPIX-FR), Italian 
(PAIPIX-IT) and German (PAIPIX-DE).

PAIPIX 7 is based on Debian Etch (4.0) although all packages in the 
paipix repository are made available for sid(unstable), lenny(testing) 
and etch(stable).

PAIPIX is build both for 32bit (i386-686) and 64bit (amd64 ? intel ET64) 
architectures. The 64 bit support, although newer, is is rather complete 
except mainly (in Etch) the browser Java and Flash plugins.

PAIPIX 7 is free (as in speech) software and results from a 
collaboration between the SIM Research Laboratory at F. Ci?ncias, of the 
Universidade de Lisboa and the SEE-FUTURE spin-off. The source code for 
all PAIPIX packages is available from the paipix repository, together 
with the compiled versions.
The patches to the live-helper package are available in the 
paipix-helper package.

As an aggregation of mostly free-software packages, you can only use 
PAIPIX at your own risk. The Author can not accept any responsibility on 
any problem or hardware damage or data loss that can result from PAIPIX 
usage.
