>Improved compatibility with other Unixes/Linuxes... A quick check reveals that OpenBSD presently has separate /bin and /sbin. FreeBSD also has a separate /lib

  The idea is, if something hardcodes e.g. /bin/grep because it was written on a system where that's where grep is, it will suddenly start working because now grep is also accessible via /bin/grep. So it's compatibility in the sense of making things work (instead of failing over pointless differences), not in the sense of being the same.

  OpenBSD also has /usr/X11R6, where it puts the X stuff (their X distro is named Xenocara). This is another piece of legacy from back when you might want to have both /usr/X11R2 and /usr/X11R3. These days the X11R6 directory actually contains X11R7 shrug. FreeBSD used to do this too, but got rid of it in FreeBSD 6 (I think? Maybe 7? About ten years ago). Both systems install packages to /usr/local.

    Both systems install packages to /usr/local That's because "packages" in the BSD world (at least openbsd) are considered third-party options, the base system is considered static. Linux distributions don't really have the notion of a static base system with "package" addons, the distribution packages are the system.
