'''SYS'''  ''is a Linux distribution intended to be easy to use for beginners, but also including tools sufficient for advanced users.
''

== Characteristics ==

* Install DVD contains ca. 18 GB of [[LZMA]]-compressed software; ''A huge system including development, server, office, and multimedia software.
* ''Installation possible using the .iso file ''(on a hard-disc or USB key), without burn it to a DVD or need of a DVD reader.  ''A bootable USB installer also available''.
* No live CD; ''aims to install or transform most fast possible and definitively the computer to Linux''
* ''Rescue system which boots within 15 seconds and contains many tools for reparations or data saving.
* ''Backup-install system allowing users to save their personalized installation to a re-installable DVD.''
* A ''primary distro'' with ''about 1800 own packages'', including the Linux kernel, [[glibc]], [[GNU Compiler Collection|GCC]]
* ''Quick updates'' whenever convenient according to the development of Linux and open source projects;  'current' install DVDs
* ''Fast and informal problem detection and correction: SYS itself is used on its development / download server''  and by users near the development

== History ==

The origin of the distro explains its characteristics, principles and politics:
* Since 2007, to avoid problems with the parallel package and source installations, ''all new programs habitually compiled for the maintenance of the community server, were packaged, too - so the next potential step would be an install DVD''.
* ''The system had to include server, development tools, and applications for  community use''.
* ''For a huge system, instead of install and configure it conventionally for someone else, it's faster to copy it from the hard disk - or  better even, to dump an already-installed and configured system to a re-installable DVD''
* ''The problems many new users have with Linux, were observed and rigorously avoided: SYS installs automatically; networking, [[Bluetooth]], webcam support work immediately; a big number of applications'', so that the users are satisfied and don't return to the previous state. The system should can substitute any previously used system and applications (office, commerce, school, multimedia). On the first versions of the SYS DVD, the user nor was asked nor informed that the system changed.        To neighbours, friends, children were distributed the DVDs and was said them that it  contains plenty games and multimedia applications. The ''easy automatic'', ''consequent (no live-CD)'', ''definitive and irreversible  installation (deleting or disabeling the previous system)'' and satisfaction about ''enough software (no minimalistic distro)'', made that users runned the install DVDs also on computers of their friends and neighbours in turn. ''The use of SYS on its own server and by neighbours helps to perceive and correct any problems fast and informally''. SYS contributed very to the local adoption of Linux.  ''SYS started in Cayenne and Matoury in Guyana-Cayenne'', travellers leaved also many copies to north-Brazil.  Meanwhile, also some 40.000 DVDs were downloaded, and SYS is now a popular [[Linux distribution|distro]].
* Because of intolerant internet legislation,  since version 0.23-r2 ''the distro and its install and admin tools are not longer licensed, offered, supported for french users or users in France''

==Versions==

Releases occur irregularly according to the progress of the Linux kernel and open source programs.   The first version what was installed outside the comunitary server was 0.16 in '10/2007 .  Since 0.19 the installer worked good,  since 0.22 any pre-existing not-*nix-system will be only deleted if otherwhise isn't enough free space for install SYS, since 0.23-r2 the installation is possible using the .iso file or an USB key.  0.17 was the first version distributed by internet, 0.20-rc2 the first downloaded in big quantity from the first stable mirror  by distromania.  Several versions get long-term support, for them are contained service packages in the repositories

== Design ==

''The backup-install system contains a) an initramdisk with a rescue system and an installer, b) a program for lzma-compact a partition containing the system, c) a bootloader. It produces from this an install DVD.''   b) cleans the system from personal or computer-depending parts of the configuration. a) makes during the instalation only a minimum configuration and produces scripts which make a better configuration at the first run — with this method, ''the installation is fast and can't fail alone or by the user's inexperience, and the automatical first-run configuration uses the full advanced  tools of the proper system.''    Furthermore the  installer contains ''d) folders in which  can be added updated versions of the kernel or of programs or corrections'', to be applied after the installation or at the first run (at revision versions , f.ex. 0.23-r3).  In this manner, ''the distro is good maintaineable and corrections or updates can be provided very fast'', inclusive 'current' DVDs.   The lzma-compaction makes it possible to put ~18 GB on a DVD and to install such a huge system very fast definitively - in less time than a live-DVD of that size would need to start.   The installer searches automatically free space on the hard disk or re-sizes half-full partitions.  This makes the installation most easy for beginners, without the danger to lose files, whilst experts can select the rescue system for make reparations, save files, resize or make partitions, and then start the installation.

== Installation ==

''For install SYS, one only need to put the install DVD in the reader, restart the computer, and wait until the DVD comes out.''    Undetectable informations (like: the preferred language, user name, internet name and password), the installer takes over from any pre-existing system.  It's also possible to install SYS from an .iso ''file'':  move it to the main folder of any partition (hard disk or USB-key), rename it SYS_Linux.iso, open it, unpack boot/initrd.cpio.gz to /initrd, enter and start sh installiso.  It also can be download, or produced using mkimg ,  an USB-key installer SYS_Linux.img; one can copy it on an USB key (or memory chip or external/internal hard disk), and after rebooting it installs SYS using the .iso file contained on the same or on any other media.

== Package management ==

Beginners and advanced users will not need to install or to update programs so early. However, ''for install or upgrade a program, on SYS one just need to click on the .tgz file (in an internet repository, or already downloaded)''.   One also can use pkgtools or kpackage.     The tgz system (in opposite to deb and rpm) don't split programs in many packages, so that the dependences are few - and anyway they can be fulfilled by install all packages from the repository.  When a program don't run, one start it within konsole and see what is missed. Sometimes (f.ex. before dump the system to an install DVD) ''one can run libtool or kleansweep to check and install if something is  missed''.    For make own packages, it is included the script  used for make the packages in the repository. SYS has as packages politics:  ''For all essential programs, SYS   should have own packages.''  As for ''secondary'' programs, there are so many new programs or updates, which cannot be packaged all for each distro. ''With priority should be packaged such programs which not or not yet were packaged by similar distros.''  Also should be avoided any trivial re-packaging / renaming of packages from other distros. SYS is kept compatible to use them in their original form, and vice-versa ''SYS packages should run on other .tgz distros''.  SYS has about 1800 own packages among about 5000 installed packages.

== Mirrors for download (install .iso 's, packages) ==

In the repository are new versions of the most packages under .../ , older versions and some special packages (service packages) under .../old .  ''New packages one can track by sorting the repository in the browser by decreasing time''.
