Projects / JayOS


JayOS is a live CD Linux distribution intended for use as a more secure mobile environment. It uses GNU makefiles and Bash shell scripts to automate the building of a complete Linux distribution from source. The result is a turnkey solution for creating a compact, highly-customizable OS. JayOS includes many standard network security and filesystem tools, a full-blown development environment, and many programming tools and libraries including GCC, GDB, DDD, Perl, GTK+, Tcl/Tk, PHP, Ruby, Python, Qt, and Glade. It runs well on commodity hardware, and can be configured to run entirely from memory. In-RAM filesystem encryption with plausible deniability provides a more secure mobile workstation. It is based on Linux From Scratch.

        Release Notes: The distribution now tracks the latest LinuxFromScratch and BeyondLinuxFromScratch projects. It includes the base LFS system (version 6.7) and probably 85% of the development BLFS (no KDE, only GNOME). Over 700 GNU projects are used. The build documentation was updated with instructions that more accurately reflect the author's own successful build process. Support for creating bootable USB sticks for the Intel Apple Mac Mini was added. A major bug that prevented the Live CD from booting reliably under emulation or with external USB CDROM drives was fixed.

        •  15 Feb 2011 20:37

          Release Notes: This release includes images for booting Linux on a Mac Mini using USB drives only. It supports all native hardware, including Apple Airport Extreme. If you have two 1GB USB sticks and a Mac Mini, follow the brief instructions on the Website to try Linux on your Mac. This procedure was tested on a second-generation Mac Mini. YMMV with iMacs, Macbooks, and Macbook Pros, although the author has had success with the non-unibody Macbook Pro. This release will not install anything, overwrite, or even access the internal hard drive. It is completely housebroken, and safe for testing and use.

          •  17 Jan 2011 02:22

            Release Notes: This release sits on top of the stable LFS-6.6 and the development version of BLFS. Highlights include kernel 2.6.32, Xorg-7.5, and Apple wireless support.

            The www site "" no longer seems available. Is there an alternative site? I'm looking for the 20110225 version.

            If you are booting from a USB CDROM and the boot fails because the kernel is unable to find the root filesystem, boot using the following arguments:

            jayos rootdev=/dev/sr0 usrdev=/dev/sr0

            Also, there is a missing directory which prevents wireless networking. Use the following commands until the next release:

            cd /etc/sysconfig/network-devices
            cp -av ifconfig.wlan0 ifconfig.ath0
            /etc/init.d/network restart
