that's your choice as the maintainer and I am not a fanboy. OpenBSD is
objectively more secure and it's mainly due to their approach. Credit
where credit is due.
OpenBSD has weaknesses in other fields where Linux shines, but to be
honest OpenBSD always has a special place in my heart and their work is
truly inspiring.

Separation of concerns and mitigations are both approaches that should
not be made exclusively, but in concert in my opinion. I will make sure
to read the paper you pointed me to.

Your reasons are simple to understand. The main argument is to
ask: "When we add OpenBSD-specific code, why not Linux-specific code as
I gave you my 2 cents on this topic. If you disregard them, that's
okay, as I said in the original mail that you as the maintainer make
that decision. There is no canonical choice here, as I also already

In an ideal world we would have portable interfaces for this, but there
aren't. Surely ii runs without unveil() just fine, however, you have
bigger problems when you need a good source of entropy that is secure
to "tap".

Anyway, I didn't want to explode this thread. Dimitris and Hiltjo also
expressed their positions on this and gave very good reasons, so in the
end the decision to externalize the patches into the wiki is supported
by the majority, including myself. :)
