Back in the day, the s in /sbin and /usr/sbin meant static, not super user. All binaries in those directories were statically linked. https://www.osnews.com/story/25556/understanding-the-bin-sbin-usrbin-usrsbin-split/ http://lists.busybox.net/pipermail/busybox/2010-December/074114.html The tl;dr is that the meaning of /sbin and /usr/sbin was lost years ago.
