  • TrueOS

    Free BSD FreeBSD Website

    TrueOS is a user friendly desktop Operating System based on Small FreeBSD iconFreeBSD .

    Known widely for its stability and security in server environments, FreeBSD provides an excellent base on which to build a desktop operating system.

    Rolling release based on FreeBSD-CURRENT.
    Weekly package/ISO updates (or more often, as necessary).
    Only one package repository. Update when you’re ready and never get left behind again.
    Automatic updates can be enabled/disabled as desired.
    All updates are performed in a safe manner using Boot Environments. Updates never change your live system, as the updated system is not activated or used until you reboot
    Existing PC-BSD/FreeBSD users can use the non-destructive fresh installation into a new boot environment on non-encrypted ZFS pools. This mechanism preserves all user data while performing a fresh install of the operating system and all applications. Simply re-create any user accounts post-installation to access the data in their home directories
    TrueOS Desktop pre-installs a pure Qt5 system based around the Lumina desktop and SysAdm.
    TrueOS Server pre-installs the SysAdm service for remote system management, with remote access initially disabled.
    A full repository of applications is available for installation through AppCafe.
