Parabola (officially known as Parabola GNU/Linux-libre) is a computer operating system based on the Arch Linux distribution for the i686, x86-64 and MIPS64 architectures. It includes the GNU OS tools and the Linux-libre kernel instead of the generic Linux kernel using completely free software. The development focuses on simplicity, community involvement and use of the latest free software packages. Parabola GNU/Linux-libre is listed by the Free Software Foundation as a completely free operating system.
Parabola GNU/Linux-libre uses a rolling release model, such that a regular system update is all that is needed to obtain the latest software. Parabola employs a social contract that commits the project to the free software community, democracy, to view itself as only competing against nonfree software and to respect Arch Linux's philosophy of simplicity.
Parabola was originally proposed by members of the gNewSense IRC channel in 2009. Members of different Arch Linux communities, especially Spanish-speaking members, started the development and maintenance of the project software and documentation.
In February 2012 Dmitrij D. Czarkoff reviewed Parabola for OSNews. Czarkoff reported that on his test computer a number of hardware problems surfaced, due to lack of free firmware. He said "That effectively means that many devices are not supported in Parabola. Eg., after installing it on my Acer Aspire One 531h netbook I couldn't use my Broadcom bluetooth module and Intel's WiFi/WiMax Link 5150 adapter. (I still could use my HTC Magic with a custom Gingerbread ROM as a USB 3G/WiFi modem, though having something always connected to USB port is pretty annoying on laptop and specifically on netbook.)" Czarkoff also criticized the lack of documentation available for Parabola. He concluded "The overall impression of the Parabola GNU/Linux user experience exactly matches the one of Arch: a system with easy and flexible installation and configuration process and good choice of free software packages. Though the lack of documentation spoils the user experience, the Arch Linux resources can be used to further configure and extend the distribution. If my hardware would allow, I would probably stick with Parabola."
Until version 4.0.0, Parabola's package manager lacked support for signed packages. Signed packages and metadata were not verified for authenticity by pacman during the download-install process. Without package authentication checking, tampered-with or malicious repository mirrors can compromise the integrity of a system. Pacman 4 allowed verification of the package database and as of April 2012 every package is signed.
Differences from Arch Linux
The project uses only 100% free software from the official Arch Linux repositories for the i686 and x86-64 architectures. It uses free replacements when possible, such as the Linux-libre kernel instead of the generic Linux kernel.
