I have to wonder how useful Landlock will be without more coverage per the above. It would be helpful if you could outline a threat model for this initial version, so people can get an idea of what kind of useful protection may be gained from it. Are there any distros or other major users who are planning on enabling or at least investigating Landlock? Do you have any examples of a practical application of this scheme? -- James Morris <jmor...@namei.org>
