I see /usr/X11R6 and it brings back memories of when Linux distros separated X in such a manner. Then I realized that r6 is kinda old.

OpenBSD's X distribution (xenocara) is based on X11R7.7 + updated components, it's just a historical naming convention. Other systems have merged X into /usr or /usr/local, OpenBSD kept the install prefix.

OpenBSD does not run the X server as root, so it does have a security benefit over more modern systems.

I understand that their malloc conversion from sbrk to mmap flushed out some long-standing X bugs as well.

Do you remember what distro used to do this?

All of them that I can remember. Note that this is from the '90s. At some point they all merged the X stuff into /usr. Maybe it was with the x.org switch, as XFree86 does indeed mention /usr/X11R6 in the docs.

Ah, you meant as a directory. Sure, I remember that, I just thought you meant as a partition.
