More information about the /usr migration, can be found at: * https://wiki.debian.org/UsrMerge * https://www.freedesktop.org/wiki/Software/systemd/TheCaseForTheUsrMerge/ One of the interesting points made in the above is that merging /bin and /usr/bin, et. al., was first done by Solaris 11 (ten years ago) and so one of the arguments for Linux distributions for proceeding with the /usr merge was to improve cross compatibility with legacy commercial Unix systems. So obviously, like so many other things, it's all Oracle's fault. :-) - Ted
