If Theo stopped being so resistant to solutions like AppArmor, then OpenBSD could have a real security layer instead of toys like unveil and pledge.

Here is Justine's write up on pledge and why he wants to port it to Linux. https://justine.lol/pledge/

It has its uses I guess, but it requires opt-in which is a pretty big disadvantage, and then still can't do even a fraction of what SELinux can already do. SELinux isn't that hard to learn, and the security benefits are immense.

    apparmor module is loaded.

including firefox and chromium

But apparmor is more complex system and in fact is an RBAC. unveil(2) is much more easier in implementation and enforcing.
