The release of the distribution Sabayon Linux 13.04, which combines the convenience for the end user with the flexibility of Gentoo is presented.
Sabayon Linux is designed as a Live-distribution, provided with the possibility of easy installation on your hard drive. The set comes complete with full set of multimedia codecs and restricted drivers for video cards, wireless adapters and software modems. Sabayon uses the modified rolling-model of preparation of updatings which does release of updatings more predictable and less painful.
The new release is notable for the development of the migration process on GitHub and the change in the numbering scheme releases – instead of the serial number is assigned, is now used the scheme with the year and month of release. Another important change is the integration of experimental support system manager systemd. Support systemd is implemented in the form of options (enabled by specifying parameter real_init = / bin / systemd at boot time), default is still used by the system initialization OpenRC. Future releases will replace systemd OpenRC, but the possibility of using OpenRC as an alternative system will be maintained. Among advantages of use of systemd reduction of time of loading by 4 times.
Other features of the Sabayon Linux 13.04:
– Announcement stable boot support on systems with EFI / UEFI, including systems with mode enabled UEFI SecureBoot. Support for UEFI SecureBoot implemented using the loader Shim, designed by Matthew Garrett (Matthew Garrett) and signed by key Microsoft, which avoids the trouble of installing and loading distribution on systems that originally shipped with Windows 8. When you first boot Live-image on a system with UEFI SecureBoot the user will be prompted to select a test switch Sabayon, which is located in the directory “/ SecureBoot”. During the installation of the new keys are generated and placed in the / BOOT / EFI / sabayon / enroll-this.cer, these keys are needed to confirm the initial boot mounted distribution. Generation of individual keys other than the keys supplied with the Live-way, will allow the user to sign the components of the system without depending on the distribution of developers;
– Upgrading packages: GNOME 3.6.3, KDE 4.10.2, MATE 1.6, LibreOffice 4.0;
– Providing full support for ZFS in the kernel Linux, due to the integration in the distribution of kernel modules created by the project ZFSOnLinux. Load modules ZFS is made at an early stage of system initialization, allowing you to use ZFS on the root partition and a swap partition placed in the pool ZFS;
– The distribution comes with the kernel Linux 3.8.8, optimized to perform desktop tasks. The composition of the base kernel was integrated set of patches, previously shipped with the experimental kernel Fusion. In particular, the included patches with support for the Task Scheduler BFS, I / O scheduler BFQ, Reiser4, experimental patches for Btrfs and DRM, driver wireless-next. As an I / O scheduler is enabled by default BFQ iosched. Neperenesennyh of patches marked the realization of hibernation, developed the project Tuxonice. Optional packages are shipped with Linux-kernel that is optimized for use on the server or to deploy isolated containers on the basis of OpenVZ or Vserver;
– /tmp partition is now mounted using tmpfs with options “nodev, noexec, nosuid” to improve security;
– The package base of a distribution kit is synchronized with a collection of Gentoo portage and is completely compatible to Portage 2.2 (EAPI2), the user is able to install software from source code as well as using the binary packages compiled for platforms ARMv7, x86 and x86-64. For x86 and x86-64 in the repository, there are about 14,000 packets, and for ARMv7 – more than 2,000. Support packages are updated continuously (rolling-release), giving the user access to the latest versions of programs. For package management GUI interface prepared “Rigo” and a console program “equo”. To use the installer to install a distribution based on the source code of the project Anaconda, developed in the framework of Fedora Linux.
Distribution is available in assemblies with KDE 4.10.2 (2.4 GB), GNOME 3.6.3 (1.9 GB), MATE 1.6 (1GB) and the Xfce 4.10 (1.6 GB).
Additionally prepared edition:
– SpinBase (470 MB) – the “text” version of the distribution is the minimum base for building custom systems to fit their needs;
– CoreCDX (540 MB) – Ready for a minimalist version for low-end PCs with graphical environment Fluxbox (users CoreCDX and SpinBase have the ability to quickly install desktop environments GNOME, KDE, Xfce or E17);
– ServerBase (490 MB) – the assembly to create a server system, which differs from SpinBase using kernel Linux 3.8, optimized for server tasks.
In addition, support is provided by the profile of Gentoo Hardened, aiming to build packages with options to improve security (for example, included additional checks on buffer overflows and randomization in the allocation of memory). HardenedServer assembly prepared to install the server version of Sabayon with active Hardened-profile.
