That's /home. /usr is just "more system space". /usr was user data, back in the day. /home came about much later. > And this article never actually explains sbin. Or /usr/share, which is interesting because as I understand it it's designed to be shareable between multiple computers of possibly different architectures sbin was created in SYS Vr4 to move all the binaries that were in /etc. /usr/share was created to move all the non-binary, non-text files that were in /etc like termcap and timezone info.
