History
ROCK Linux was started in the summer of 1996 by Claire Wolf.[3] T2 SDE was forked in 2004, when developers were dissatisfied with the project.[4] ROCK Linux was discontinued in 2010.[5]
In August 2006, version 6.0 was released with ISO images for AMD64, i386, PPC64 and SPARC64.[6] In July 2010, version 8.0 (codenamed "Phoenix") was released.[7] In April 2021, version 21.4 was released.[8] In July 2022, version 22.6 was released.[9] In April 2024, version 24.5 was released. In June 2024, version 24.6 was released shipping Wine for Windows application compatibility as well as LibreOffice and Mozilla Thunderbird for a complete Linux desktop experience. In July 2024, version 24.8 was released shipping OpenJDK for Java compatibility as well as a multi-architectural MIPS64 Linux kernel built for SGI IP27, IP30, IP32 (r5k & r10k) as the first Linux OS release to boot on multiple SGI RISC workstations and servers. In December 2024, version 24.12 was released with initial support for running on Nintendo Wii U, improved SPARC64 and IA-64 stability, an improved global t2 package manager frontend and various other improvements. In April 2025, version 25.4 was released with worlds-first demonstrating AMD's ROCm HPC/AI stack running on RISC-V and ARM64. In October 2025, version 25.10 was released expanding the base package set to a full Wayland desktop for most architectures and significantly improving IA-64 and SPARC64 stability.
Usage
Puppy Linux has used T2 SDE for compiling their packages.[10] AskoziaPBX has used a fork of T2 SDE because it had support for Blackfin.[11] Archivista made a document management system based on T2 SDE.[12]
Hardware support
T2 SDE supports the x86-64, x86, arm64, arm, RISC-V (32 and 64 bit), ppc64le, ppc64-32, sparc64, MIPS64, mipsel, hppa, m68k, alpha, and ia64 architectures.[8] The PowerPC platform is well supported. There are ISO images available, or users can build it themselves.[13]
T2 SDE is known for its wide, exotic and vintage hardware support and has been shown to run on the Nintendo Wii.[14] It also supports the SGI Octane[15] and the PlayStation 3.[16]
