Syllable Server is a small, efficient server operating system built to be similar to Syllable Desktop, but on the Linux kernel. Due to its light weight, Syllable Server is exceptionally suitable as a virtualisation platform for running other operating systems (or multiple instances of itself), using the QEMU emulator.
Kaj de Vos has announced the release of Syllable Server 0.4, a small (but extensible) server distribution built on top of a recent Linux kernel and the Linux From Scratch (LFS) base system: "We are pleased to announce that we have released the new Syllable Server 0.4. This release focuses on maturing existing functionality, improving security, ongoing system restructuring, and making the system a suitable base for third-party package managers. About half the packages in the system were upgraded, including key components such as the Linux kernel, udev, the LFS init scripts, DirectFB, SDL, Bash, Packager, OpenSSH, REBOL/Core, the Cheyenne web server and cdrtools. Other important packages such as Ruby, Midnight Commander, Links and Transmission were also updated. XZ-Utils was added, providing the same LZMA compression as in 7-Zip
