The 2026.09 release provides fresh software packages from Debian testing/forky. As usual it also incorporates up to date hardware support and fixes known bugs from previous Grml releases. About the codename. Important changes: This release is based on Debian testing/forky as of September 2026. GNU Screen 5.0.1 landed. The required configuration changes are not backwards compatible. Users of our grml screenrc must either upgrade or use the screenrc_v4 file with GNU Screen 4.9. New and removed features. New software since the Grml 2026.04 release is included, and we continued to clean up the house. Noteworthy changes are: grml-live - build system for creating Grml (based) Linux live systems: grml-live now requires Linux user namespaces in the build environment. Unfortunately docker and other containerization tools do not provide Linux user namespaces inside containers. This was prompted by systemd changes, and took a substantial effort. Daily images were not built between 2026-06-10 and 2026-09-02. Reading configuration from grml-live.conf was removed.
