OnWorks Mandriva online is a full-featured Linux desktop and server, sponsored by the OpenMandriva Association. It was based on ROSA, a Russian Linux distribution project which forked Mandriva Linux in 2012, incorporating many of Mandriva's original tools and utilities and adding in-house enhancements. The goal of OpenMandriva is to facilitate the creation, improvement, promotion and distribution of free and open-source software in general, and OpenMandriva projects in particular
As you can see in this OnWorks Mandriva online its most important features are:
Mandriva Linux contained the Mandriva Control Center, which eases configuration of some settings. It has many programs known as Drakes or Draks, collectively named drakxtools, to configure many different settings. Examples include MouseDrake to set up a mouse, DiskDrake to set up disk partitions and drakconnect to set up a network connection. They are written using GTK+ and Perl, and most of them can run in both graphical and text mode using the ncurses interface.
Mandriva Linux 2011 was released only with KDE Plasma Desktop, whereas other desktop environments were available but not officially supported. Older Mandriva versions also used KDE as standard but others such as GNOME were also supported.
Mandriva Linux used a package manager called urpmi, which functions as a wrapper to the .rpm binaries. It is similar to apt from Debian & Ubuntu, pacman from Arch Linux, yum or dnf from Fedora in that it allows seamless installation of a given software package by automatically installing the other packages needed. It is also media-transparent due to its ability to retrieve packages from various media, including network/Internet, CD/DVD and local disk. Urpmi also has an easy-to-use graphical front-end called rpmdrake, which is integrated into the Mandriva Control Center.
