List of Linux distributions endorsed by the Free Software Foundation

Technical variations of Linux distributions include support for different hardware devices and systems or software package configurations. Organizational differences may be motivated by historical reasons. Other criteria include security, including how quickly security upgrades are available; ease of package management; and number of packages available.

These tables compare each active and noteworthy distribution's latest stable release on wide-ranging objective criteria. It does not cover each operating system's subjective merits, branches marked as unstable or beta, nor compare Linux distributions with other operating systems.

Basic general information about the distributions: creator or producer, release date, the latest version, and such. References are not added here but can be found in respective articles.

Linux distributions endorsed by the Free Software Foundation are marked 100% Free under the System distribution commitment column.

The table below shows the default file system, but many Linux distributions support some or all of ext2, ext3, ext4, Btrfs, ReiserFS, Reiser4, JFS, XFS, GFS2, OCFS2, and NILFS. It is possible to install Linux onto most of these file systems. The ext file systems, namely ext2, ext3, and ext4 are based on the original Linux file system.

File systems have been developed by companies to meet their specific needs, by hobbyists, or adapted from Unix, Microsoft Windows, and other operating systems. Linux has full support for XFS and JFS, FAT (the DOS file system), and HFS, the main file system for the Macintosh. Support for Microsoft Windows NT's NTFS file system has been developed and is now comparable with other native Unix file systems. CDs, DVDs, and Blu-ray discs' ISO 9660 and Universal Disk Format (UDF) are supported.
