0.3.4 - Filesystem UUID

12 Oct 13:21
Choose a tag to compare

ISO Downloads

This release focuses on changes to RedoxFS, the bootloader, and the kernel to enable filesystem UUIDs.

The basic logic is this:

  • The bootloader loads the kernel from RedoxFS on the disk it is present on
  • The bootloader passes the UUID as an environmental variable to the kernel
  • The kernel passes the environmental variables to the init process
  • The init script for the init filesystem passes this UUID as an argument to RedoxFS
  • RedoxFS searches all available disks for a filesystem matching this UUID, and mounts it as the root filesystem

This was particularly important for the installation of Redox.

0.3.3 - Lower Memory Usage

This release brings much lower memory usage with ISO - 480 MB instead of 1300 MB. There are also other bug fixes, features, and improvements.

Download the ISO here.

VirtualBox with Intel PRO/1000 Ethernet will be the most feature-complete experience. Only 64-bit x86 systems are supported. Give the VM at least 1 GB of RAM for the best results. The default username is user with an empty password. There is also a root user with a password of password.

As many of the changes are related to self hosting, by @ids1024, I have named this release POSIXLY_CORRECT. Most changes are managed independently from this repository, making it difficult to track them all. More detailed information can be found in news articles since the last release:

This release runs best if you can meet the following requirements:

  • 2 GB RAM
  • 32 MB VRAM
  • PS/2 Mouse and Keyboard
  • Intel 8254x Ethernet
  • Intel HDA audio

0.3.0 - The Return of the Redox

Discussion on Reddit


It has been a while since our last release, on April 22! I cannot possible represent all of the changes to Redox OS since then, so the best way to experience them is to try it out yourself! I have listed the changes I think are biggest below. Here are the changes to our distribution repository since 0.2.0

This release was particularly challenging. The build process has been switched over to using the cookbook, and a cross compiler is now used instead of a gcc wrapper script located here. These two changes required a large amount effort to make the system compile correctly and easily again, and to get Travis builds to work. Improvements have been made to the kernel, ion, newlib, and many other projects.


However, due to this effort, we can now produce Redox installations from the same recipes that produce package builds, meaning that every file in a default Redox install has been installed by a package, and can be managed by the package manager. Due to a change in the bootloader allowing the kernel to be loaded from RedoxFS, this will also include the kernel soon.

To view all of the currently available packages, view the repository listing, or the repository description file


Also, due to using a real cross compiler for the build, we have been able to significantly improve support for C software. Massive steps have been made in the direction of self-hosting, with the porting of binutils, newlib, gcc, nasm, llvm, and rustc to Redox. Work, mostly by @ids1024, is currently focusing on porting git. This has also identified and fixed many problems with our POSIX support, and improved the overall functionality of Redox.

Posts from @ids1024 about self-hosting can be found here:


In addition to these two changes, the kernel has been improved. @CWood1 has written a shiny, new ACPI stack that includes an AML parser. This allows shutdown on Redox to be done correctly on nearly all systems. Support for the HPET has also been added, with a fallback to the PIT when it is not present. Eventually I hope that we will be able to correctly suspend and resume Redox by running the parsed AML.


Ion has gone through a huge amount of development, mostly by @mmstick, who has been maintaining it. There have been 139 commits to ion since the last release, adding new syntax, improving bugs, and adding new features. View them here


In addition, This Week in Redox has been restarted by @goyox86. Here are the articles since the last release:

0.2.0 - 2 Years of Redox

🎉 🍰 As of 2017-04-20, Redox OS has been on GitHub for two years! 🍰 🎉

Due to the number of positive changes that have happened, the version has been bumped to 0.2!

Please discuss this release on Reddit.

The most major changes are an increase in kernel performance, a complete implementation of frame allocation (and deallocation) in the kernel, a new sys:iostat to inspect all open file handles, resizing and scrolling in the editor, and more ion shell features.

This list of changes came from a line-by-line review of all changes since 0.1.5, which was released 13 days before this release.
