About

Grml is a Debian based live system focusing on the needs of system administrators. The 2025.08 release provides fresh software packages from Debian trixie. 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 the Debian 13 Release named “trixie”.
• We use a new signing key for the deb.grml.org repositories
• The grml-live build system incorporated the previously separate packages grml-autoconfig, grml-etc, grml-scripts, grml-udev-config.
• boot options lang= and the grml-lang tool have been fixed.
