- gilgamesh3 2y ago>OpenBSD has had it since forever. OpenBSD introduced mimmutable in OpenBSD 7.3, which was released 10/4/2023 (for US people, it would be 4/10/2023), so it isn't "forever". Meanwhile Linux and FreeBSD has "memfd_create" forever while OpenBSD doesn't have anonymous files and relies on "shm_open".
- pushupentry1219 2y ago> OpenBSD introduced mimmutable in OpenBSD 7.3 Correct but they did have a very similar syscall for a long time that they deprecated after the release of mimmutable iirc
