[$] SUSE's efforts to disable setuid system-wide

Setuid (and setgid) binaries have long been a source of headaches, and security vulnerabilities, on Linux systems.

They are largely seen as something to be avoided; SUSE's security team, for example, forbids the inclusion of setuid or setgid binaries in packages unless they have been reviewed and explicitly allowed. Thorsten Kukuk wants to go a step further and disallow them entirely.

At the 2026 All Systems Go! conference, he spoke about his work to disable setuid system-wide, as well as some of the hurdles that remain.
